In order to enable a user to see a watermark information dynamic desalting process in a watermark desalting process so as to improve the diversity of picture display, the embodiment of the invention provides a watermark processing method, which comprises the steps of firstly identifying watermark information of a picture to be processed; determining the first transparency of the watermark information of each first picture in the N first pictures corresponding to the picture to be processed according to the first initial value and the first termination value of the transparency of the watermark information; the first transparency corresponding to the watermark information in each first picture is different, and the first termination value is smaller than the first initial value; and then, in a first playing time period, sequentially playing N first pictures according to the first transparency from high to low. In the first playing time period, the transparency of watermark information in N played first pictures is gradually decreased from high to low, so that a user can see the dynamic desalination process of the watermark information in the first playing time period, and the diversity of picture display is improved.

The watermark information in the picture refers to that some other information is added in the picture. For example, in the embodiment of the present invention, watermark information in a picture mainly refers to content such as homonymous numbers, characters, frame graphics, etc. added in the picture, and these watermark information are commonly used for propagating advertisement information.

The technical scheme of the invention is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

Fig. 1 is a schematic flow chart of a watermark processing method according to an embodiment of the present invention, where the watermark processing method may be executed by a watermark processing apparatus, and the watermark processing apparatus may be set independently or may be set in a terminal. For example, referring to fig. 1, the method for processing the watermark may include:

s101, identifying watermark information of a picture to be processed.

By way of example, the watermark information may include the type of watermark information, the color of the watermark information, and the location of the watermark information. The watermark information may be digital, textual, or both digital and textual.

Optionally, when watermark information in the picture to be processed is identified, watermark information in the picture to be processed can be identified through a watermark identification technology, or a watermark identification model can be constructed in advance, and the watermark information in the picture to be processed can be identified through the watermark identification model; of course, the watermark information in the to-be-processed picture may be identified in other manners, and the embodiment of the present invention is merely described by taking the watermark information in the to-be-processed picture identified by the watermark identification technology or the watermark information in the to-be-processed picture identified by the watermark identification model as an example, but the embodiment of the present invention is not limited thereto. The watermark recognition model may be built offline for the terminal.

For example, when watermark information in a picture to be processed is identified through a watermark identification model, the type of the watermark information, the color of the watermark information and the position of the watermark information in the picture to be processed can be identified, and the format of the watermark information can be JSON format and stored in an array form.

Taking watermark information as a digital number of 123456 as an example, identifying the picture to be processed through a watermark identification model to obtain watermark information of 123456 in the picture to be processed, wherein the watermark information of 123456 can be expressed in a format of 6 groups of numbers; wherein, the array corresponding to the number "1" is: [ { type: 'number', value: '1', color: 'yellow', location: { top: xx1, left: xy1, bottom: yx1, right: yy1} ]; the array corresponding to the number "2" is: [ { type: 'number', value: '2', color: 'green', location: { top: xx2, left: xy2, bottom: yx2, right: yy2} ]; … …; similarly, the array corresponding to the number "6" is: [ { type: 'number', value: '6', color: 'red', location: { top: xx6, left: xy6, bottom: yx6, right: yy6} ]. It can be seen that the location area where each number 1 is located is a rectangular area.

After watermark information in the picture to be processed is identified by the watermark identification model, the following S102 may be performed:

s102, determining the first transparency of watermark information of each first picture in N first pictures corresponding to the picture to be processed according to the first initial value and the first termination value of the transparency of the watermark information.

The first transparency corresponding to the watermark information in each first picture is different, the first termination value is smaller than the first initial value, and N is a positive integer greater than or equal to 2. For example, N may be determined according to the first play period and the play speed. The first playing period may be understood as a period of time required for a user to view the transparency of watermark information in N first pictures from the first initial value to the first termination value. For example, when the first playing period may be 200ms and the playing speed is that one picture is played every 2 ms, it is determined that 100 first pictures may be played within the 200ms, that is, N is equal to 100.

The first initial value may be understood as a current transparency value of the watermark information in the picture to be processed after the picture to be processed is acquired. For example, the first initial value of the transparency of the watermark information may be 1, and the first termination value may be 0.5, and of course, the first initial value and the first termination value may also be other values, which may be specifically set according to practical needs, where the embodiment of the present invention only uses the first initial value of the transparency of the watermark information may be 1, and the first termination value may be 0.5 as an example for illustration, but the embodiment of the present invention is not limited thereto.

It should be noted that, in the embodiment of the present invention, each of N first pictures corresponding to a picture to be processed is the picture to be processed, and only the transparency of watermark information in each first picture is different from the transparency of watermark information in the picture to be processed.

After determining the first transparency of the watermark information of each of the N first pictures corresponding to the to-be-processed picture according to the first initial value and the first termination value of the transparency of the watermark information, in a first playing time period, sequentially playing the N first pictures according to the first transparency from high to low, namely executing the following S103:

and S103, in a first playing time period, sequentially playing N first pictures according to the first transparency from high to low.

For example, after determining the first transparency of the watermark information of each of the 100 first pictures corresponding to the to-be-processed picture according to the first initial value 1 and the first termination value 0.5 of the transparency of the watermark information, the 100 first pictures can be sequentially played according to the first transparency from high to low within the first playing time period of 200 ms. As the transparency of the watermark information in the 100 first pictures which are sequentially played in 200ms is gradually decreased from high to low, a user can see the dynamic desalination process of the watermark information in 200ms, and the diversity of picture display is improved.

Therefore, the watermark processing method provided by the embodiment of the invention firstly identifies the watermark information of the picture to be processed; determining the first transparency of the watermark information of each first picture in the N first pictures corresponding to the picture to be processed according to the first initial value and the first termination value of the transparency of the watermark information; the first transparency corresponding to the watermark information in each first picture is different, and the first termination value is smaller than the first initial value; and then, in a first playing time period, sequentially playing N first pictures according to the first transparency from high to low. In the first playing time period, the transparency of watermark information in N played first pictures is gradually decreased from high to low, so that a user can see the dynamic desalination process of the watermark information in the first playing time period, and the diversity of picture display is improved.

In order to more clearly describe how to determine the first transparency of the watermark information of each of the N first pictures corresponding to the to-be-processed picture according to the first initial value and the first termination value of the transparency of the watermark information in the embodiment of the present invention, for example, as shown in fig. 2, fig. 2 is a schematic flow diagram of another processing method of the watermark provided in the embodiment of the present invention, where the processing method of the watermark may further include:

S201, determining a first transparency interval of watermark information of two adjacent pictures according to a first initial value, a first termination value and N of transparency of watermark information.

It is understood that the first transparency intervals of watermark information of two adjacent pictures may be equal or unequal. For example, the first transparency interval between the 2 nd picture and the 3 rd picture may be equal to or not equal to the first transparency interval between the 3 rd picture and the 4 th picture. For convenience of description, in the embodiment of the present invention, description will be given by taking an example that first transparency intervals of watermark information of two adjacent pictures are equal.

For example, taking watermark information as "123456", the first initial value of transparency of watermark information as 1, the first termination value as 0.5, and n as 100 as an example, according to that transparency of watermark information in 100 first pictures is gradually decreased from the first initial value 1 to 0.5, a first transparency interval of watermark information of two adjacent pictures in 100 pictures can be calculated.

After the first transparency interval of the watermark information of the two adjacent pictures is calculated, the first transparency of the watermark information of each of the N first pictures corresponding to the to-be-processed picture may be determined according to the first transparency interval, that is, the following S202 is executed:

S202, determining the first transparency of watermark information of each first picture in N first pictures corresponding to the pictures to be processed according to the first transparency interval.

For example, in combination with the description in S201, after the first transparency interval 0.005 is calculated, the first transparency of watermark information in each of 100 first pictures may be determined according to the first transparency interval 0.005. The first transparency of the watermark information in the 1 st first picture is 1, the first transparency of the watermark information in the 2 nd first picture is 0.995, the first transparency of the watermark information in the 3 rd first picture is 0.990, the first transparency of the watermark information in the 4 th first picture is 0.985, and so on, and the first transparency of the watermark information in the 100 th first picture is 0.5, so that the first transparency of the watermark information of each of the 100 first pictures is obtained.

After obtaining the first transparency of the watermark information in each of the 100 first pictures, the 100 first pictures can be sequentially played within the first playing time period of 200ms according to the first transparency of the watermark information in each of the 100 first pictures from high to low. Since the transparency of watermark information in 100 first pictures played in 200ms is gradually decreased from high to low, users can see the dynamic desalination process of watermark information in 200ms, and thus the diversity of picture display is improved.

It can be understood that, in the first playing period, when N first pictures are sequentially played according to the first transparency of the watermark information in each first picture from high to low, for the first pixel point belonging to the watermark information, the first pixel point is played according to the first transparency of the watermark information in the first picture, and for the second pixel point not belonging to the watermark information, the second pixel point is played according to the first initial value, for example, please refer to fig. 3, fig. 3 is a schematic flow chart of playing N first pictures provided in the embodiment of the invention, where the method may include:

s301, determining position information of watermark information in each of N first pictures.

For example, when determining the position information of the watermark information in the first picture, the watermark identification model may identify the first picture, so as to obtain the type of the watermark information, the color of the watermark information, and the position information of the watermark information. The position information of the watermark information can be represented by coordinates of four points, namely an upper point, a lower point, a left point and a right point, of the watermark information, and the position of the obtained watermark information is a rectangular area.

Taking watermark information as '123456' as an example, identifying the picture to be processed through a watermark identification model, so as to obtain watermark information '123456' in the picture to be processed, wherein the watermark information '123456' can be expressed in a format of 6 groups of numbers; wherein, the array corresponding to the number "1" is: [ { type: 'number', value: '1', color: 'yellow', location: { top: xx1, left: xy1, bottom: yx1, right: yy1} ]; the array corresponding to the number "2" is: [ { type: 'number', value: '2', color: 'green', location: { top: xx2, left: xy2, bottom: yx2, right: yy2} ]; … …; similarly, the array corresponding to the number "6" is: [ { type: 'number', value: '6', color: 'red', location: { top: xx6, left: xy6, bottom: yx6, right: yy6} ]. It can be seen that the location area where each number is located is a rectangular area.

After determining the region information where the watermark information is located in the first picture, the following S302 may be performed:

s302, respectively matching the color of each pixel point in the position information with the color of the watermark information in the first picture, and determining a first pixel point matched with the color of the watermark information in the first picture and a second pixel point not matched with the color of the watermark information in the first picture.

It can be understood that in the embodiment of the present invention, color matching may be understood as the same color, or may be understood as the colors are different, but are relatively close and almost the same, specifically may be set according to actual needs, and the embodiment of the present invention is not limited further herein.

After the position information of the watermark information in the first picture is obtained through the step S301, the color of each pixel point in the position information of the watermark information is matched with the color of the watermark information, and if the color of the first pixel point in the position information of the watermark information is matched with the color of the watermark information, the first pixel point is indicated to be the pixel point in the watermark information; conversely, if the color of the second pixel point in the position information where the watermark information is located is not matched with the color of the watermark information, the second pixel point is not the pixel point in the watermark information, so that the first pixel point matched with the color of the watermark information in the first picture and the second pixel point not matched with the color of the watermark information in the first picture can be determined.

Taking watermark information as "123456" as an example, each pixel point in the position area where the number "1" is located may be first matched with the color of the watermark information, and since the position area corresponding to the number "1" is an area formed by { top: xx1, left: xy1, bottom: yx1, right: yy1}, the area includes a plurality of pixel points, each pixel point in the area may be matched with the color of the number "1", if the color of the first pixel point in the area where the number "1" is located is matched with the color of the number "1", it is indicated that the first pixel point is a pixel point in the number "1"; conversely, if the color of the second pixel point in the area where the number "1" is located does not match the color of the number "1", it is indicated that the second pixel point is not the pixel point in the number "1". Then, each pixel point in the position area where the number "2" is located can be matched with the color of the number "2", and because the position area corresponding to the number "2" is an area formed by { top: xx2, left: xy2, bottom: yx2, right: yy2}, each pixel point in the area can be matched with the color of the number "2", if the color of the first pixel point in the area where the number "2" is located is matched with the color of the number "2", the first pixel point is the pixel point in the number "2"; conversely, if the color of the second pixel point in the area where the number "2" is located does not match the color of the number "2", it is indicated that the second pixel point is not the pixel point in the number "2". The color of each pixel point in the area where each number in the watermark information "123456" is located can be matched in turn similarly, so as to obtain a first pixel point matched with the color of the watermark information and a second pixel point not matched with the color of the watermark information in the position information of the watermark information "123456".

After determining the first pixel point matching the color of the watermark information in the first picture and the second pixel point not matching the color of the watermark information in the first picture, respectively, the following S303 may be performed:

s303, playing the first pixel point according to the first transparency of the watermark information in the first picture, and playing the second pixel point according to the first initial value.

In connection with the above description in S302, in matching the color of each pixel in the region where the number "1" in the first picture is located with the color of the number "1", matching the color of each pixel in the region where the number "2" is located with the color of the number "2", matching the color of each pixel in the region where the number "3" is located with the color of the number "3", matching the color of each pixel in the region where the number "4" is located with the color of the number "4", matching the color of each pixel in the region where the number "5" is located with the color of the number "5", respectively, after the color of each pixel point in the region where the number '6' is located is matched with the color of the number '6', playing the first pixel point according to the first transparency of the watermark information in the first picture, namely when playing 100 first pictures from high to low according to the first transparency, wherein the first transparency of the first pixel point in the 1 st first picture is 1, the first transparency of the first pixel point in the 2 nd first picture is 0.995, the first transparency of the first pixel point in the 3 rd first picture is 0.990, the first transparency of the first pixel point in the 4 th first picture is 0.985, and the like, and the first transparency of the first pixel point in the 100 th first picture is 0.5; meanwhile, for the second pixel point which does not belong to the watermark information in the first picture, the second pixel point is played according to the first initial value, namely when 100 first pictures are played according to the first transparency from high to low, the first transparency of the second pixel point in the 1 st first picture is 1, the first transparency of the second pixel point in the 2 nd first picture is 1, the first transparency of the second pixel point in the 3 rd first picture is 1, the first transparency of the second pixel point in the 4 th first picture is 1, and the like, so that when 100 first pictures are played in the first playing time period, only the first pixel point in the 100 first pictures are played according to the sequence of the first transparency from high to low, and in the playing process, the transparency of the second pixel point in the 100 first pictures is kept unchanged, so that the transparency of the second pixel point in the 100 first pictures is not reduced due to the lower transparency of the pixel point in the watermark information, and other pixel points in the lower quality area of the picture are not reduced.

Therefore, in the embodiment of the invention, when playing N first pictures, judging whether the color of each pixel point in the position information of the watermark information in the first pictures is matched with the color of the watermark information or not so as to determine a first pixel point matched with the color of the watermark information in the first pictures and a second pixel point not matched with the color of the watermark information in the first pictures; and then, playing the first pixel point according to the first transparency of the watermark information in the first picture, and playing the second pixel point according to the first initial value. In the first playing time period, the transparency of the first pixel points in the N played first pictures is gradually decreased from high to low, so that a user can see the dynamic desalination process of watermark information in the first playing time period, and the diversity of picture display is improved. In addition, the transparency of the second pixel points in the N first pictures is kept unchanged, so that the transparency of the first pixel points in the watermark information is not reduced along with gradual reduction of the transparency of the first pixel points, and the quality of the pictures is improved.

Based on the embodiment shown in any one of fig. 1 to 3, since the transparency of watermark information in N first pictures played in the first playing time period is gradually decreased from high to low, a user can see the dynamic desalination process of watermark information in the first playing time period, thereby improving the diversity of picture display. In order to improve the quality of the finally displayed picture, a user can further acquire the picture without watermark, the second transparency of watermark information of each piece of second picture in M pieces of second pictures corresponding to the picture to be processed can be determined according to the first termination value and the second termination value of transparency of watermark information, and the target pixel increment of watermark information of each piece of second picture can be determined according to the second initial value and the third termination value of pixel increment of watermark information; and then, in a second playing time period, sequentially playing M second pictures according to the second transparency from low to high and the target pixel increment, so that the finally played second picture does not contain watermark information any more, and a user can see the process of dynamically dissolving the watermark information in the second playing time period. For example, referring to fig. 4, fig. 4 is a flowchart of another method for processing watermark information according to an embodiment of the present invention, where the method for processing watermark information may further include:

S401, determining second transparency of watermark information of each second picture in M second pictures corresponding to the pictures to be processed according to the first and second termination values of transparency of the watermark information.

The second transparency corresponding to watermark information in each of M second pictures is different, the first termination value is smaller than the second termination value, and M is a positive integer greater than or equal to 2. For example, M may be determined according to the second play period and the play speed. The second playing time period may be understood as a time period required for a user to view the watermark dissolving process in the M second pictures. For example, when the second playing period may be 200ms and the playing speed is that one picture is played every 2 ms, 100 second pictures may be played within the 200ms, that is, M is equal to 100.

Optionally, when determining the second transparency of the watermark information of each of the M second pictures corresponding to the to-be-processed picture according to the first termination value and the second termination value of the transparency of the watermark information, the second transparency interval of the watermark information of two adjacent pictures may be determined according to the first termination value, the second termination value and the M of the transparency of the watermark information; and determining the second transparency of the watermark information of each second picture according to the second transparency interval.

It is understood that the second transparency intervals of watermark information of two adjacent pictures may be equal or unequal. For example, the second transparency interval between the 2 nd picture and the 3 rd picture may be equal to or not equal to the second transparency interval between the 3 rd picture and the 4 th picture. For convenience of description, in the embodiment of the present invention, an example will be described in which the second transparency intervals of watermark information of two adjacent pictures are equal.

For example, taking the watermark information as "123456", the transparency of the watermark information is a first termination value of 0.5, the second termination value is 1, and m is 100 as an example, according to the transparency of the watermark information in 100 second pictures, the transparency of the watermark information in the 100 second pictures is gradually increased from the first termination value of 0.5 to the second termination value of 1, so that the second transparency interval of the watermark information in two adjacent pictures in the 100 pictures can be calculated. After the second transparency interval of 0.05 is calculated, the second transparency of watermark information in each of the 100 second pictures can be determined according to the second transparency interval of 0.005. Wherein the second transparency of the watermark information in the 1 st second picture is 0.5, the second transparency of the watermark information in the 2 nd second picture is 0.505, the second transparency of the watermark information in the 3 rd second picture is 0.51, the second transparency of the watermark information in the 4 th second picture is 0.515, and so on, the second transparency of the watermark information in the 100 th second picture is 1, thereby obtaining the second transparency of the watermark information of each of the 100 second pictures.

S402, determining the target pixel increment of the watermark information of each second picture according to the second initial value and the third termination value of the pixel increment of the watermark information.

For example, the second initial value of the pixel increment may be 0%, and the third ending value may be 100%, and of course, other values may also be used, where the embodiment of the present invention only uses the example that the second initial value of the pixel increment may be 0%, and the third ending value may be 100% as an example, and may be specifically set according to actual needs, and the embodiment of the present invention is not limited further. Where the pixel increment may be represented by beta.

Optionally, when determining the target pixel increment of the watermark information of each second picture according to the second initial value and the third termination value of the pixel increment of the watermark information, determining the pixel increment interval of the watermark information of two adjacent pictures according to the second initial value, the third termination value and M of the pixel increment of the watermark information; and determining the target pixel increment of the watermark information of each second picture according to the pixel increment interval.

It will be appreciated that the pixel increment intervals of watermark information for two adjacent pictures may or may not be equal. For example, the pixel increment interval between the 2 nd and 3 rd pictures may be equal to or not equal to the pixel increment interval between the 3 rd and 4 th pictures. For convenience of description, in the embodiment of the present invention, an example will be described in which pixel increment intervals of watermark information of two adjacent pictures are equal.

Also for example, taking watermark information as "123456", the second initial value of the pixel increment may be 0%, the third ending value may be 100%, and M is 100 as an example, according to that the pixel increment of watermark information in 100 second pictures is gradually increased from the second initial value of 0% to the third ending value of 100%, the pixel increment interval of watermark information of two adjacent pictures in 100 pictures may be calculated to be 1%. After the pixel increment interval of the watermark information is calculated to be 1%, the target pixel increment of the watermark information in each of the 100 second pictures can be determined according to the pixel increment interval of 1%. Wherein the target pixel increment of watermark information in the 1 st second picture is 0%, the target pixel increment of watermark information in the 2 nd second picture is 1%, the target pixel increment of watermark information in the 3 rd second picture is 2%, the target pixel increment of watermark information in the 4 th second picture is 3%, and so on, the target pixel increment of watermark information in the 100 th second picture is 100%, thereby obtaining the target pixel increment of watermark information of each second picture in the 100 second pictures.

It should be noted that, in the embodiment of the present invention, there is no sequence between S401 and S402, and S401 may be executed first, and then S402 may be executed. S402 may be executed first, and S401 may be executed later; of course, S401 and S402 may be performed simultaneously, and the embodiment of the present invention will be described by taking S401 and S402 as examples, but the embodiment of the present invention is not limited thereto.

After determining the second transparency and the target pixel increment of the watermark information of each second picture, M second pictures can be sequentially played in the second playing time period according to the second transparency of the watermark information of each second picture from low to high and the target pixel increment, namely, the following S403 is executed:

s403, in a second playing time period, M second pictures are sequentially played according to the second transparency from low to high and the target pixel increment.

In combination with the descriptions in S401 and S402, after obtaining the second transparency of the watermark information and the target pixel increment of each of the 100 second pictures, respectively, 100 second pictures can be sequentially played within the second playing time period of 200ms according to the second transparency from low to high and the corresponding target pixel increment. As the target pixel increment of watermark information in 100 second pictures which are sequentially played is gradually increased within 200ms and the second transparency of the corresponding watermark information is gradually increased, a user can see the dynamic dissolving process of the watermark information within 200ms under the condition of ensuring better picture quality, thereby improving the diversity of picture display.

It can be understood that, in the second playing period, when M second pictures are played in turn according to the second transparency from low to high and the target pixel increment, for a third pixel point belonging to watermark information, the third pixel point is played according to the second transparency of the watermark information and the target pixel increment in the second picture, and for a fourth pixel point not belonging to the watermark information, the fourth pixel point is played according to the current color of the first initial value and the fourth pixel point. For example, referring to fig. 5, fig. 5 is a schematic flow chart of playing M second pictures according to an embodiment of the present invention, where the method may include:

s501, determining position information of watermark information in each second picture in the M second pictures.

It can be understood that the position information of the watermark information in the first picture is the same as the position information of the watermark information in the second picture, and specifically, reference may be made to the description related to S301, and here, the embodiment of the present invention will not be described in detail.

It should be noted that, when playing M second pictures, S501 may not be executed to determine the location information of the watermark information in the second pictures, but the location information of the watermark information determined in S301 may be directly used.

S502, respectively matching the color of each pixel point in the position information with the color of the watermark information in the second picture, and determining a third pixel point matched with the color of the watermark information in the second picture and a fourth pixel point not matched with the color of the watermark information in the second picture.

It can be understood that the method for respectively matching the color of each pixel in the location information with the color of the watermark information is similar to the method for respectively matching the color of a plurality of pixels in the location information with the color of the watermark information in S302, and specifically, reference may be made to the related description in S302, and detailed description of the embodiment of the present invention is omitted.

It should be noted that, when determining whether each pixel in the position information where the watermark information is located is a pixel of the watermark information, S502 need not be executed, but it may be determined whether each pixel in the position information where the watermark information is located is a pixel of the watermark information directly according to the matching result obtained in S302.

S503, determining a target color corresponding to the third pixel point according to the target pixel increment of the watermark information of the second picture.

Optionally, when determining the target color corresponding to the third pixel according to the target pixel increment of the watermark information of the second picture, the colors of a plurality of fifth pixels around the third pixel may be obtained, where the fifth pixels are pixels not belonging to the watermark information; and determining a target color corresponding to the third pixel point according to the current color of the third pixel point, the average value of the colors of the plurality of fifth pixel points and the target pixel increment. For example, the colors of the fifth pixel points may be three or four, and may be specifically set according to actual needs, where the embodiment of the present invention is not limited specifically.

For example, the colors of four fifth pixel points not belonging to watermark information around the third pixel point may be obtained respectively, and an average avg of the colors of the four fifth pixel points may be calculated, and then according to the current color rgb of the third pixel point, the average avg of the colors of the four fifth pixel points, and the target pixel increment beta of the third pixel point, rgb+ (avg-rgb) is calculated, so as to obtain the target color of the third pixel point, where the target color of the third pixel point is the playing color of the third pixel point in the second playing time period.
