Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the present invention relates to a clipping method, which is applied to an electronic device, wherein the electronic device may be a terminal such as a mobile phone or a computer, or a server, and the present invention is not limited in this embodiment. The following describes implementation details of the clipping method of the present embodiment in detail, and the following is provided only for easy understanding and is not necessary for implementing the present embodiment.
A flowchart of the clipping method in the present embodiment is shown in fig. 1, and specifically includes:
step 101: and acquiring the time period of the terminal which is continuously triggered.
Wherein, the terminal plays the video to be edited; the video to be edited can be an offline video cached in the terminal or an online video, and the online video can be an online on-demand video or an online live video. It should be noted that, in this embodiment, the online video may be directly edited without downloading the online video to the local and then editing the online video, so that the online video is edited more conveniently, simply and conveniently. In addition, the terminal can be a mobile phone, a notebook computer, a tablet computer and the like. For convenience of explanation, the terminal in this embodiment and the following embodiments is exemplified by a mobile phone, but the present invention is not limited to this. The handset being continuously triggered may be: the method comprises the following steps that the screen of the mobile phone is continuously pressed, a volume key on the side face of the mobile phone is continuously pressed, a preset virtual button on the screen of the mobile phone is continuously pressed, the body of the mobile phone is continuously positioned at a preset angle with the horizontal plane, the mobile phone continuously receives a preset voice instruction and the like; the preset virtual button, the preset angle and the preset voice indication can be set according to actual needs, and the embodiment is not particularly limited.
In one example, the mobile phone is continuously triggered, specifically, the mobile phone continuously receives a preset voice indication, and the preset voice indication may be a cheering sound or a laughing sound of the user. For example, when a user is watching a video, a continuous cheering sound may be emitted when a highlight occurs, and a continuous laughing sound may be emitted when a laughing segment occurs. The mobile phone can take the time period of receiving the continuous cheering or laughing as the time period which is continuously triggered, so that the video segments played in the time period can be clipped in the subsequent steps. That is to say, the mobile phone can automatically clip the video segment causing the user to make cheering or laughing, so that the user can conveniently review the automatically clipped wonderful segment or laughing segment at any time, and the user experience can be improved.
Specifically, the mobile phone may start timing when detecting that the mobile phone is just triggered, end timing when detecting that the mobile phone is stopped triggering, and a time period obtained by the timing is a time period during which the mobile phone is continuously triggered.
In a specific implementation, before the obtaining of the time period in which the terminal is continuously triggered is performed, it may be determined whether the terminal enters the clipping mode. In an example, when it is detected that a preset physical button or a virtual button is clicked during a process of playing a video by the terminal, the terminal may be considered to enter a clip mode, and the preset physical button or the virtual button may be set according to actual needs to remind a user that the button is pressed and then the terminal will enter the video clip mode, but this embodiment is not particularly limited to this. In another example, the terminal may be considered to enter the clipping mode if a voice instruction from the user indicating that the clipping mode may be entered is received while the terminal is playing a video. The voice command may be preset according to actual needs, and this embodiment is not particularly limited to this. It should be noted that, for convenience of description, the present embodiment provides two implementation manners for determining that the terminal enters the clipping mode, and in a specific implementation manner, the implementation manner for determining that the terminal enters the clipping mode is not limited to the above two manners.
In one example, the electronic device may be a terminal, and the terminal may acquire a time period for which the terminal is continuously triggered after detecting that the terminal enters the clip mode. In another example, the electronic device may be a server, and the terminal may acquire a time period during which the terminal is continuously triggered after detecting that the terminal enters the clip mode, and then transmit the acquired time period to the server.
Step 102: and determining the video segments of the video to be clipped played in the time period.
That is to say, in the process of playing the video to be clipped, it is determined which video segment in the video to be clipped is played in the time period in which the terminal is continuously triggered.
In one example, the time period is a time period during which the mobile phone continuously receives laughter or cheering of the user, and the video segment determined in the time period is a video segment causing the cheering or laughter of the user.
Step 103: and clipping the determined video segments to obtain clipped videos.
Specifically, the determined video segment is a video segment needing to be clipped, the time stamp of the start video frame of the video segment is extracted as a clipping start time point, the time stamp of the end video frame of the video segment is extracted as a clipping end time point, and the video segment between the clipping start time point and the clipping end time point is clipped to obtain a clipped video.
In one example, the clipped video may be automatically stored in a preset storage space in the terminal, for example, may be stored in a gallery in the mobile phone, so that the user can conveniently view the clipped video after the clipping is completed.
It is worth mentioning that the terminal can control the playing speed of the video to be clipped being played according to the pressure of the screen being pressed, so that the clipping speed can be controlled according to the actual requirement. Specifically, if it is detected that the screen of the terminal is pressed, the pressing pressure when the screen is pressed may be detected, and the playing speed corresponding to the pressing pressure is obtained according to the pressing pressure, so as to play the video to be edited at the obtained playing speed. For example, a pressure sensor may be disposed below a screen of the terminal, the pressure sensor detects the pressing pressure, a corresponding relationship between the pressing pressure and the playing speed may be pre-stored in the terminal, and the playing speed of the video being played is adjusted according to the detected pressing pressure at the current moment.
In one example, the manner of obtaining the play speed corresponding to the pressing pressure may be: and calculating the playing speed corresponding to the pressing pressure according to the pressing pressure, the preset speed doubling gear range and the pressure detection range of the terminal. The preset speed-doubling gear range can be set according to actual needs, and the embodiment is not particularly limited. For example, the preset speed range is [0.2, 5], which means that the playing speed of the video may be between 0.2 and 5 times. The pressure detection range of the terminal may be a pressure detection range of a pressure sensor built in the terminal.
In one example, the play speed corresponding to the pressing pressure may be calculated according to the following formula:
vt＝((Nmax-Nmin)(pt-pmin)/(pmax-pmin)+Nmin)v0
wherein v istFor calculated play speed, ptTo pressing pressure, NmaxAnd NminUpper and lower limits, p, of the playing multiple speed gear range, respectivelymaxAnd pminUpper and lower limit values, v, of the pressure detection range, respectively0The playing speed corresponding to the playing speed with the speed doubling gear being 1. For example, a pressure sensor in the terminal can acquire the pressing pressure of the user in the tth second in real time and record the pressing pressure aspt，ptThe video playback speed between the tth second and the t +1 th second can be determined, i.e. in accordance with ptAnd playing the video between the tth second and the t +1 th second at the calculated playing speed.
In one example, the terminal being continuously triggered may specifically be that a screen of the terminal is continuously pressed. In this case, a video segment played during a period in which the screen is continuously pressed may be regarded as a video segment that needs to be clipped. The pressure of the screen being pressed can be used as a determining factor of the playing speed of the video to be edited being played by the terminal, and the larger the pressing pressure is, the faster the playing speed is.
The above examples in the present embodiment are only for convenience of understanding, and do not limit the technical aspects of the present invention.
Compared with the prior art, the method and the device have the advantages that when the video needs to be edited, the terminal can be continuously triggered, the video segment played by the terminal in the time period continuously triggered can be regarded as the determined segment needing to be edited, the determined segment needing to be edited can be edited, the user can conveniently edit the segment needing to be edited at any time in the process of watching the video, and convenience in editing is improved. Moreover, the segment to be clipped is determined according to the time period of continuous triggering of the terminal, manual attention is not needed, the progress bar of video playing is dragged back and forth, the starting time point and the ending time point of the clip are determined more easily and rapidly, and therefore the speed of clipping is increased. Moreover, the user can directly complete the clipping of the video segment played in the time period of continuously triggering the terminal through the continuously triggering terminal in the process of watching the online video without downloading the online video, so that the clipping convenience is further improved. In addition, in the embodiment, the video playing speed in the video clipping process can be controlled based on the pressure of the screen being pressed, which is beneficial to controlling the clipping speed according to actual needs.
A second embodiment of the present invention relates to a clipping method. The following describes implementation details of the clipping method of the present embodiment in detail, and the following is provided only for easy understanding and is not necessary for implementing the present embodiment.
A flowchart of the clipping method in the present embodiment is shown in fig. 2, and specifically includes:
step 201: acquiring the time period for which the screen of the terminal is continuously pressed.
For example, after entering the clip mode, the terminal may start timing from when a built-in pressure sensor detects that the screen is pressed, and stop timing when the screen is detected to stop pressing, so as to obtain a time period for which the terminal is continuously pressed.
Step 202: and determining the video segments of the video to be clipped played in the time period.
That is, a video clip of a video to be clipped played by the terminal during a period in which the terminal is continuously pressed is determined.
Step 203: a starting video frame of a video segment is obtained.
Specifically, the starting video frame of the video clip is a video picture played by the terminal when the terminal screen is just pressed, that is, a first frame video image of the video clip. The terminal can perform a frame dropping operation on the video segment, thereby intercepting the starting video frame.
Step 204: objects in the starting video frame that are located within the area where the screen is pressed are identified.
Specifically, the starting video frame may be subjected to instance segmentation based on a Mask-RCNN algorithm, that is, the first frame video image of the video segment determined in step 202 is subjected to instance segmentation to obtain the areas occupied by different objects in the first frame video image in the image; wherein, the different objects can be human beings, animals, plants, etc. Then, it can be recognized what object is specifically in the area where the screen is pressed in the first frame of video image, for example, what object is specifically to which the user's finger presses the touch point of the screen. It should be noted that, in this embodiment, the example segmentation of the starting video frame based on the Mask-RCNN algorithm is only used as an example, and the specific implementation is not limited thereto.
Step 205: and clipping each video frame containing the object in the video segment.
In one example, if the number of objects located in the area where the screen is pressed in the identified starting video frame is 1, the identified object may be taken as an object of interest to the user. During the period that the user continuously presses the screen, firstly, the face detection, the face recognition and the target detection can be carried out on each frame of video image played; the method comprises the steps of detecting a human face existing in a video image, identifying the detected human face, and detecting a target object except the human face. It is then determined whether each frame of video image contains an object of interest to the user. Finally, each video frame containing the object of interest to the user is clipped.
In one example, the appearance time point and the disappearance time point of the object of interest to the user may be determined according to whether each adjacent video frame in the video segment contains the object of interest to the user. For example, for any two consecutive video images, that is, each adjacent video frame, if the previous video image contains an object of interest to the user and the next video image does not contain an object of interest to the user, the timestamp of the next video image may be extracted and recorded as the vanishing time point. Similarly, if the previous frame of video image does not contain an object of interest to the user and the next frame of video image contains an object of interest to the user, the timestamp of the next frame of video image may be extracted and recorded as the point in time of occurrence. If multiple sets of appearance time points and disappearance time points are determined, which indicates that an object interested by a user appears and disappears in a video segment played during the continuous pressing period, a video frame played between each set of appearance time points and disappearance time points can be clipped. For example, a video frame from the first "appearance point" to the first "disappearance point" is cut into a video segment 1, a video frame from the second "appearance point" to the second "disappearance point" is cut into a video segment 2, and so on, which is beneficial to fast cutting to obtain a video segment containing an object of interest of the user.
In one example, when the number of the objects located in the area where the screen is pressed in the identified starting video frame is multiple, the area occupied by each object in the starting video frame may be acquired, and the object with the smallest area may be used as the target object. And then clipping each video frame containing the target object in the video segment. For example, referring to fig. 3, it is assumed that fig. 3 is a cut starting video frame, and an area actually pressed by the user is an a area. It can be seen that the object located in the area a in fig. 3 has a person and a dog, and the area occupied by the person and the area occupied by the dog in the figure can be obtained separately. As can be seen from fig. 3, the area occupied by the dog is the smallest of the two objects in the area a, and the dog can be used as the target object really interested by the user. Finally, when clipping, it is possible to identify each frame of video image played during the period in which the user continuously presses the screen, identify whether the dog in fig. 3 is included, and clip each frame of video including the dog in fig. 3, so that each frame of the clipped video includes the dog in fig. 3.
In another example, when the number of objects located in the area where the screen is pressed in the identified starting video frame is plural, the object in the front layer may be selected as the target object, and each video frame containing the target object in the video segment determined in step 202 may be clipped. The object in the front layer is more likely to be the object really interested by the user, so that the object in the front layer is selected as the target object, each video frame containing the target object is clipped, and the video segment really interested by the user is easier to be clipped.
In one example, the manner of selecting an object in the front layer as a target object may be as follows: determining the pixel color of the area occupied by each different object, extracting the pixel color of the overlapping area occupied by each different object, comparing the pixel color of the overlapping area with the pixel color of the area occupied by each different object, and taking the object in the area with the highest pixel color similarity with the overlapping area as the object in the layer close to the front layer. For example, referring to fig. 3, it is assumed that fig. 3 is a cut starting video frame, and an area actually pressed by the user is an a area. It can be seen that the object located in the area a in fig. 3 has a person and a dog, and the pixel colors of the areas occupied by the person and the dog in the figure can be respectively obtained, and it is assumed that the pixel color of the area occupied by the person is black, and the pixel color of the area occupied by the dog is brown. As can be seen from fig. 3, there is an overlapping area in the area occupied by the person and the dog, and the pixel color of the overlapping area of the person can be extracted, assuming that the extracted pixel color of the overlapping area is brown. In summary, it can be found that the pixel color similarity between the overlapping region and the region where the dog is located is higher, and then the dog in fig. 3 can be used as the object in the selected layer closer to the front layer, that is, the dog in fig. 3 can be used as the finally determined target object.
It should be noted that, in this embodiment, the above two examples are provided only to illustrate how to determine one target object among a plurality of objects, but the specific implementation is not limited to the above two examples. Any manner of determining a target object among a plurality of objects is within the scope of the present embodiment.
It should be noted that the above examples in the present embodiment are merely illustrative for easy understanding, and do not limit the technical aspects of the present invention.
Compared with the prior art, in the embodiment, the continuous trigger on the terminal can be embodied as continuous pressing on the screen of the terminal, at the moment when the screen is just pressed, the object in the pressing area in the video is taken as the object interested by the user, namely the target object, and the video frames in the clipped video clip are all the video frames containing the target object, so that the video clip containing the object interested by the user can be conveniently and accurately clipped. In addition, considering the possibility of object overlapping, namely, a plurality of objects in the pressed area in the initial video frame are provided, and the object with the smallest area is most likely to be the object really interested by the user, therefore, the object with the smallest area is taken as the target object, and each video frame containing the target object is clipped, which is more beneficial to clipping the video really interested by the user. Moreover, the embodiment also provides another method for determining the target object which is possibly interested in the user among the multiple objects in a mode of similarity of pixel colors, so that the implementation mode of the embodiment is flexible and various.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
