Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following further explains the image processing method provided by the present invention with specific embodiments, which are not limited to the embodiments of the present invention.
Referring to fig. 1, a flowchart of an embodiment of a picture processing method according to an embodiment of the present invention is shown. As an embodiment, the method may be applied to a server, that is, a publisher of a picture, and as shown in fig. 1, the process may include the following steps:
As an embodiment, the target area to be hidden may be marked in the original picture manually by the user. For example, the user may frame out the target area to be hidden in the original picture through a picture processing tool. Based on this, the server may determine the area manually marked by the user as the target area to be hidden.
As another embodiment, the server may automatically mark the target area to be hidden in the original picture according to a set rule. Here, the setting rule may be, for example: the area where the face is located is determined as a target area, the area where the sensitive characters are located is determined as a target area, and the like, which are not limited in the embodiment of the present invention.
It should be noted that, in the embodiment of the present invention, the number of the target areas in one original picture is not limited, that is, in this step 101, one or more target areas to be hidden may be determined in the original picture.
And 102, splicing the original picture and the area information of the target area by the server according to a set picture splicing mode to obtain a target picture.
And 103, the server sends the target picture to the client so that the client analyzes the original picture and the region information of the target region from the target picture, and hides the target region in the original picture according to the region information and the set hiding mode.
In one example, if the target area is a regular-shaped area, for example, a rectangular area, the area information may include: the pixel position of the upper left vertex of the target area in the original picture, and the length and width of the target area; for another example, if the target region is a circular region, the region information may include a pixel position of the center of the target region in the original picture, and a radius (or diameter) of the target region.
In another example, if the target area is an irregularly shaped area, the boundary of the target area may be divided into line segments as many as possible, and the area information of the target area includes: the pixel locations of the two end points of each line segment in the original picture.
As can be seen from the description in step 102, the target picture is formed by splicing the original picture and the region information of the target region according to a set picture splicing manner, and therefore, the target picture includes both the original picture and the region information of the target region.
Based on this, after the target picture is sent to the client, the client can analyze the original picture and the region information of the target region from the target picture, and then can determine the target region to be hidden in the analyzed original picture according to the region information of the target region, and finally can hide the target region.
How to splice the original picture and the region information of the target region according to the set picture splicing manner to obtain the target picture is described below by using the embodiment shown in fig. 2, and will not be described in detail here.
As to how the client parses the area information of the original picture and the target area from the target picture, and how to perform the hiding processing on the target area, the following is described with an embodiment shown in fig. 4, and detailed description is not given here.
The technical scheme provided by the embodiment of the invention comprises the steps of determining a target area to be hidden in an original picture at a server side, splicing the area information of the original picture and the target area according to a set picture splicing mode to obtain a target picture, sending the target picture to a client side, analyzing the area information of the original picture and the target area from the target picture by the client side, and hiding the target area in the original picture according to the area information, so that the picture which is partially hidden at the client side can be displayed to meet the user requirement, compared with the prior art, the local area in the original picture at the server side is not required to be hidden, the same original picture is not required to be configured according to different display requirements of different clients at the server side, and the complexity of product development at the server side is reduced, the storage space of the server side is also saved; because the local area in the original picture is hidden by the client according to the set hiding mode, and different clients can correspond to different hiding modes, different clients can adopt different hiding modes for the same original picture, and then the same original picture can present different display effects on different clients, thereby improving the user experience.
In addition, in the embodiment of the present invention, after the step 102 is executed to obtain the target picture, the original picture may be deleted, and since the target picture is formed by splicing the area information of the original picture and the area information of the target area, after the original picture is deleted, the original picture can be obtained from the target picture even if necessary, and at the same time, the storage space of the server can be saved.
Referring to fig. 2, a flowchart of another embodiment of a method for processing a picture according to an embodiment of the present invention is shown. The process shown in fig. 2 is based on the process shown in fig. 1, and describes how the server splices the original picture and the area information of the target area according to a set picture splicing manner, taking the original picture as the PNG picture as an example, so as to obtain the target picture. As shown in fig. 2, the process may include the following steps:
At present, the file structure of a standard PNG picture is as shown in fig. 3, and includes a PNG file flag (8 bytes), and several PNG data blocks. The PNG picture defines two types of PNG data blocks, namely a key data block and an auxiliary data block. The key data blocks are standard PNG data blocks, including a header data block (25 bytes), a palette data block, an image data block, and an end of image data block, which must be included in each PNG picture. The auxiliary data block is an optional data block such as a background color data block, an image histogram data block, a text information data block, etc. Note that the header data block is the first PNG data block in each PNG picture.
The PNG data block is then composed of four parts, as shown in table 1 below:
TABLE 1
Based on the above description, the specific implementation of step 301 may include steps 401 to 403 illustrated in fig. 4, as shown in fig. 4:
As can be seen from table 1 above, in one PNG data block, the other parts except the data block data part account for 12 bytes in total, and therefore, the set value is 12 bytes.
And 402, performing cyclic redundancy check on the area information to obtain a cyclic redundancy check code corresponding to the area information.
As can be seen from table 1, a PNG data block sequentially includes: length, Chunk Type Code, Chunk Data, and CRC, so in this step 403, the Length value of the region information, the set Data block Type value, the region information, and the CRC are sequentially written into the blank Data block, and a PNG Data block (referred to as a mask Data block in the embodiment of the present invention) including the region information is obtained. Wherein, the set data block type value may be {'t', 'e', 'x','t' }, which represents a text type.
And step 203, the server sequentially splices the file mark, the file header data block, the mask data block and other parts except the file mark and the file header data block in the original picture to obtain the target picture.
As can be seen from the above description, the header data block is the first PNG data block in each PNG picture, and each PNG picture has a PNG file flag, and the length of the PNG file flag is 8 bytes, so in step 202, the server parses the content of the first 8 bytes from the original picture, where the content of the first 8 bytes is the PNG file flag, and then, parses the content of the 25 bytes from the 9 th byte, which is the header data block, and when performing the splicing, the mask data block is spliced behind the header data block.
Through the embodiment shown in fig. 2, when the original picture is the PNG picture, the server splices the area information of the original picture and the target area according to the format of the PNG picture and the structure of the PNG data block to obtain the target picture, thereby realizing that the area information of the target area is injected into the original picture.
In addition, it should be noted that the original picture is a PNG picture, which is only an exemplary illustration, in practice, the original picture may also be a picture in other formats, for example, a picture in a JPG/JPEG format, and this is not limited in this embodiment of the present invention.
Specifically, taking a JPG picture as an example, the JPG picture has some data in the form of 0xFF, which are called "mark (Marker)", and represent JPG information data segments. The flags 0xFFE 0-0 xFFEF are called "Application Marker", which are not necessary for decoding JPG pictures and can be used for storing configuration information and the like. Based on this, in the embodiment of the present invention, the area information of the target area can be stored in the flags 0xFFE 0-0 xfffef, so as to obtain the target picture including both the original picture and the area information of the target area.
Further, after receiving the target picture, the client may analyze the area information of the target area from the flags 0xFFE 0-0 xfffef, determine the content of other bytes as the original picture, and then hide the target area in the original picture according to the analyzed area information and the set hiding manner.
Referring to fig. 5, a flowchart of another embodiment of a picture processing method according to an embodiment of the present invention is provided. As an embodiment, the method may be applied to a client, that is, a presentation end of a picture, and as shown in fig. 5, the process may include the following steps:
In this step 502, taking the original picture as the PNG picture and obtaining the target picture according to the splicing sequence described in the above step 203 as an example, a process of the client analyzing the region information of the target region from the target picture is explained:
first, the client reads first content of a first set length from a first specified byte in the target picture. Here, since the mask data block is located after the PNG file flag and the header data block, the first byte of the mask data block is the 34 th byte of the target picture, that is, the first specified byte refers to the 34 th byte. The first set length is 4 bytes, and the first content includes a data field in the mask data block, that is, a length of the area information (hereinafter, referred to as a second set length). At this point, the client obtains the length of the region information in the mask data block.
Further, reading second content of a second set length from a second specified byte in the target picture, and determining the second content as area information of the target area. Here, as is apparent from the PNG data block structure shown in table 1, since the region information in the mask data block starts at the 5 th byte in the mask data block, the second designated byte is the 39 th (34+5) byte.
In the target picture, the parts except the mask data block are the contents in the original picture, so that the client can analyze the original picture after analyzing the mask data block from the target picture. As to how the client further parses and renders the original picture, those skilled in the art can refer to the related description in the prior art, and details are not described here.
In this step 503, the client may first determine a target region to be hidden from the parsed original picture according to the parsed region information, and then hide the target region according to a set hiding manner.
As an embodiment, the client hiding the target area in the original picture according to the set hiding manner includes: and the client recalculates the pixel value of each pixel point in the target area by using the set mask kernel operator. It can be understood that the change of the pixel value of each pixel point in the target region means that the original image is hidden.
As another embodiment, the client hiding the target area in the original picture according to the set hiding manner includes: the client covers the target area by using the set picture so as to hide the target area. Here, the setting picture may be, for example, an emoticon picture, a full white picture, a monochrome color picture, or the like.
As another embodiment, the client hiding the target area in the original picture according to the set hiding manner includes: the client performs mosaic processing on the target area to realize hiding processing on the target area.
It should be noted that, because the target area is not of a fixed size, when the client uses the setting picture to cover the target area, the client may first adjust, for example, enlarge or reduce, the setting picture according to the size of the target area, so as to avoid the phenomenon of incomplete hiding or excessive hiding.
In addition, it should be noted that the hiding manner corresponding to the client may be fixed or may be dynamically changed, for example, the hiding manner corresponding to the client may be set or changed by a user of the client according to preferences and habits of the user, or for example, a plurality of hiding manners may be set on the client side, and the effective time of each hiding manner is set, and at most only one hiding manner is in an effective state at the same time point (for example, hiding manner 1 is effective on monday to wednesday, and hiding manner 2 is effective on thursday to saturday), then, when the client performs hiding processing on the target area in the original picture, the hiding manner currently in the effective state is adopted. In addition, if there is no hidden mode in an effective state currently, the client may choose not to hide the target area in the original picture.
Further, the hiding modes corresponding to different clients may be the same or different. For example, one client performs hiding processing on the target area by using a mosaic processing method, and another client performs hiding processing on the target area by using a picture covering method, which is not limited in the embodiment of the present invention. It can be understood that, by performing the hiding process on the target area in the same original picture in different hiding manners, different display effects will be exhibited.
The technical scheme provided by the embodiment of the invention comprises the steps of determining a target area to be hidden in an original picture at a server side, splicing the area information of the original picture and the target area according to a set picture splicing mode to obtain a target picture, sending the target picture to a client side, analyzing the area information of the original picture and the target area from the target picture by the client side, and hiding the target area in the original picture according to the area information, so that the picture which is partially hidden at the client side can be displayed to meet the user requirement, compared with the prior art, the local area in the original picture at the server side is not required to be hidden, the same original picture is not required to be configured according to different display requirements of different clients at the server side, and the complexity of product development at the server side is reduced, the storage space of the server side is also saved; because the local area in the original picture is hidden by the client according to the set hiding mode, and different clients can correspond to different hiding modes, different clients can adopt different hiding modes for the same original picture, and then the same original picture can present different display effects on different clients, thereby improving the user experience.
