Referring to fig. 1, an embodiment of the present invention provides a video control method applied to an electronic device, where the video control method includes:
In this embodiment of the present invention, the target video may be a video locally stored in the electronic device, or may also be a network video that needs to be connected to a network for watching, which is not specifically limited in this embodiment of the present invention.
In the embodiment of the invention, the user can select the target video to be watched from the electronic equipment locally or on the network and play the target video. During the playing of the target video, the electronic device may identify a first object in a video picture of the target video in real time through a correlation algorithm of target identification, where the first object may include a person, an animal, an object, and the like.
In the embodiment of the present invention, the electronic device may determine, from each first object, a target object that a user wants to focus on, where the number of the target objects may be 1 or N, where N is an integer greater than 1.
And 104, marking the picture area where the target object is positioned.
In the embodiment of the invention, the electronic device can specially mark the picture area where the target object is located in the process of playing the target video, for example, the outline of the target object can be marked by a colored solid line or a colored dotted line, so that the picture area where the target object is located is distinguished from other picture areas of the target video, and a user can quickly focus on the target object from each first object.
In the embodiment of the present invention, a user may control an image area where a target object is located through a zoom gesture, a click on a zoom button, and the like, and in a case where the user performs a zoom/move gesture for the image area, or clicks on the zoom/move button, the electronic device may receive a first input for zooming/moving the image area where the target object is located. It should be noted that the embodiment of the present invention does not specifically limit the operation manner and the operation position of the first input.
And 106, responding to the first input, and controlling the picture area to zoom and/or move.
In the embodiment of the invention, the electronic equipment responds to the first input, and can control the picture area where the target object is located to perform operations such as reduction, amplification, movement and the like, so that a user can freely switch the size and the display position of the picture area where the target object is located in the process of playing the target video, and the user can conveniently watch the details and the whole situation of the video picture. It should be noted that the zoom-in/zoom-out operation and the movement operation may be controlled simultaneously through a first input, or may be controlled separately through different inputs, which is not limited in this embodiment of the present invention.
In the embodiment of the invention, the electronic device can identify each first object in the video picture in the process of playing the target video, then determine the target object in each first object, and further mark the picture area where the target object is located in the process of playing the target video. After that, the electronic device may receive a first input of the user, and in response to the first input, may control the screen region where the target object is located to zoom and/or move. In the embodiment of the invention, the electronic equipment can mark the picture area where the specific object is located in the video playing process, and can control the picture area where the specific object is located to zoom and/or move according to the user requirements, so that the user can focus on the specific object while watching the video without pausing the video for screenshot viewing, the operation of observing the specific object in the video is simplified, and the efficiency of focusing on the specific object is improved. In addition, because the video pictures do not need to be converted into pictures, the continuity of the context of the video pictures can be kept while paying attention to specific objects, and the user experience is improved.
Referring to fig. 2, another embodiment of the present invention provides a video control method applied to an electronic device, where the video control method includes:
This step is similar to the implementation of step 101 described above and will not be described in detail here.
In the embodiment of the invention, the user can select the target video to be watched from the electronic equipment locally or on the network and play the target video. In the process of target video playing, the electronic device can identify each first object in the video frame by using an example segmentation algorithm based on target identification, and mark the same object in different video frames as the same type. Specifically, the electronic device may frame different object instances in a video frame through a target detection algorithm, and then perform pixel-by-pixel labeling in different instance regions through a semantic segmentation algorithm, to finally obtain a picture region of each instance object in a video picture. Furthermore, the same object in each video frame can be marked as a class through an image feature matching algorithm, so that the object tracking can be realized.
Each algorithm in the embodiments of the present invention can refer to the related art, and is not described in detail herein.
In the embodiment of the invention, the electronic device is provided with the album application, the electronic device can read the target picture in the album application, and in the specific application, the user usually focuses on the person, so the target picture can include the picture containing the person in the album application. In addition, the target picture may also be a picture selected manually by the user or selected by the set filtering condition, such as a picture in the last 3 months. Of course, in order to avoid missing objects that may be of interest to the user, the target picture may also be all pictures in the album application, and this is not specifically limited in the embodiment of the present invention.
It should be noted that the album application may include any application having a picture storage function, such as a beauty camera application, a drawing application, and the like, and the corresponding album may store the pictures in the application.
In step 204, each second object in the target picture is identified.
In the embodiment of the present invention, the electronic device may identify the second object in each acquired target picture through a target identification related algorithm, and the specific manner may refer to the identification manner of the first object, which is not described herein again in the embodiment of the present invention. The second object may include a person, an animal, an object, and the like.
In step 205, in the case where it is determined that the first object exists in the respective second objects, thumbnail images of the first object existing in the respective second objects are generated.
In the embodiment of the invention, the electronic equipment can match the first objects identified in the video picture with the second objects identified in the album application picture one by one, so that the objects which are most likely to be interested in the user in each first object can be screened out.
For example, the first object and the second object are both characters, the electronic device may sequentially match each character image (i.e., each first object) identified in the video image with the face clustering result (i.e., each second object) in the album application, if a certain character image identified in the video image also exists in the album application of the user, the character may be presumed to be an object that the user wants to focus on, and according to the rule, an object that the user may be interested in may be screened out from each first object.
In a case that it is determined that the first object exists in each of the second objects, it is indicated that an object that may be of interest to the user exists in the target video, and the electronic device may generate a thumbnail of the first object existing in each of the second objects, that is, a thumbnail of the object that may be of interest to the user.
In the embodiment of the invention, the electronic equipment can screen out the objects which are possibly interested by the user in advance according to the clustering result of the video content and the photo album application, so that the efficiency of selecting the focused object by the user is improved. In addition, due to the fact that the photo album pictures of different users are different, thumbnails of the same target video presented on electronic equipment of different users are different, and the intelligent personalized recommendation effect can be achieved.
In the embodiment of the invention, the electronic equipment can display the thumbnails of the objects which are possibly interested by the user, so that the objects which can focus on can be recommended to the user, and the efficiency of selecting the focused objects by the user is improved.
Alternatively, the electronic device may display the respective thumbnails by: displaying each thumbnail in a preset display area outside a video picture; or, the thumbnails are displayed in a floating mode on the video picture with preset transparency.
Referring to fig. 3, the electronic device may display each thumbnail outside the video picture in a preset display area on the left side of the video picture, that is, the display area where the video picture is located does not overlap with the preset display area where the thumbnail is located, wherein the target video may be appropriately reduced to prevent the thumbnail from shielding the video picture. In addition, the thumbnail can be displayed in a floating manner above the video picture and displayed with a certain transparency, so that the thumbnail is prevented from blocking the video picture.
In step 207, a second input is received in the case where each thumbnail is displayed.
In the embodiment of the invention, under the condition that each thumbnail is displayed, a user can check the thumbnails, and then the user can select 1 or more thumbnails to be focused in the presented thumbnails by clicking and the like, so that the electronic equipment can receive a second input of selecting the thumbnails to be focused by the user. The user can also select 1 or more thumbnails to be focused by inputting thumbnail serial numbers, so that the electronic equipment can receive a second input of selecting the thumbnails to be focused by the user. The second input is not particularly limited in the embodiments of the present invention.
In response to a second input, a target thumbnail is selected from the thumbnails, step 208.
In an embodiment of the present invention, in response to the second input, the electronic device may select a target thumbnail selected by the user through the second input from among the respective thumbnails.
In the embodiment of the invention, the electronic equipment can determine the first object corresponding to the target thumbnail as the target object which the user wants to focus on.
In addition, the user can increase or decrease the objects to be focused in real time in the process of playing the target video, and the operation is flexible and convenient.
In addition, in a case that the electronic device does not recommend the thumbnail, the user may also directly click or long-press a certain first object in the video image, and further, the electronic device may directly determine the first object selected by the user as the target object, which is not specifically limited in the embodiment of the present invention.
In the embodiment of the present invention, the electronic device may add a masking layer mark to a picture area where a target object that a user wants to focus on is located, or may mark an outline of the picture area where the target object is located with a solid line or a dotted line with color, or may perform color display on the picture area where the target object is located, perform gray scale display on other picture areas, and so on, so that the target object that the user wants to focus on may be distinguished from other objects, and the user may pay attention to the target object.
In the embodiment of the present invention, a user may control an image area where a target object is located through a zoom gesture, a click on a zoom button, and the like, and in a case where the user performs a zoom/move gesture for the image area, or clicks on the zoom/move button, the electronic device may receive a first input for zooming/moving the image area where the target object is located. It should be noted that the embodiment of the present invention does not specifically limit the operation manner and the operation position of the first input.
In response to the first input, the screen region is controlled to zoom and/or move, step 212.
In the embodiment of the invention, the electronic equipment responds to the first input, and can control the picture area where the target object is located to perform operations such as reduction, amplification, movement and the like, so that a user can freely switch the size and the display position of the picture area where the target object is located in the process of playing the target video, and the user can conveniently watch the details and the whole situation of the video picture.
For example, a user may zoom in and view a screen region where a target object is located through a two-finger zoom gesture, and may zoom in and out in a certain proportion according to a distance between two fingers with a central point of the screen region as an origin. In the process of playing the target video, a user can move the position of the picture area where the target object is located on the screen through single-finger sliding.
In addition, if the screen of the electronic device is a folding screen, the folding angle of the folding screen can be mapped into scaling and displacement factors in advance, and then the display control can be performed on the picture area where the target object is located according to the folding angle of the folding screen.
Specifically, the electronic device includes a folding screen, and the first input includes a folding operation on the folding screen, this step may be implemented by: determining a folding angle of the folding screen in response to a folding operation on the folding screen; under the condition that the folding angle meets a first preset condition, inquiring a scaling corresponding to the folding angle according to a preset scaling comparison table; under the condition that the folding angle meets a second preset condition, inquiring the displacement to be moved along the preset direction of the picture area corresponding to the folding angle according to a preset displacement comparison table; the picture area is scaled according to the scaling and/or moved according to the displacement.
The zoom ratio comparison table stores a corresponding relation between a folding angle meeting a first preset condition and a zoom ratio, and the displacement comparison table stores a corresponding relation between a folding angle meeting a second preset condition and a displacement of the picture area to be moved along a preset direction.
The target video can be displayed on only one side of the folding screen, so that the influence of the folding angle on the picture display is avoided. The user can fold the folding screen, and the folding angle of folding screen this moment can be confirmed to the electronic equipment correspondence. The first preset condition may specifically be a first angle range, and when the folding angle belongs to the first angle range, the electronic device may determine that the user needs to reduce/enlarge the image area where the target object is located, and then the electronic device may query a reduction/enlargement ratio corresponding to the current folding angle from a preset scaling ratio comparison table. The electronic device may then zoom in/out on the screen area where the target object is located according to the zoom in/out ratio obtained by the query.
The second preset condition may specifically be a second angle range, and under the condition that the folding angle belongs to the second angle range, the electronic device may determine that the user needs to move the picture area where the target object is located, and then the electronic device may query a displacement corresponding to the current folding angle from a preset displacement comparison table, where the displacement may be set as a displacement required for moving the picture area along a preset direction. And then the electronic equipment can move the picture area where the target object is located along the preset direction according to the displacement obtained by the query. The preset direction may be set and changed by a user, and this is not particularly limited in the embodiment of the present invention.
For example, the range of 0 ° to 90 ° of the folding angle may be mapped as a scaling, and the range of 90 ° to 180 ° may be mapped as a displacement of the center point of the picture region to be moved along the diagonal of the video picture.
Wherein, in a case where the first angle range and the second angle range have an overlapping range, when the folding angle of the folding screen belongs to the overlapping range, the electronic device may simultaneously control reduction/enlargement and movement of the screen region through one folding operation. Under the condition that the folding angle of the folding screen does not belong to the overlapping range and the first angle range and the second angle range do not overlap, the electronic equipment can only control one of the reduction/enlargement and the movement of the picture area through one folding operation.
In addition, the video control method does not need to modify the original video file, and the picture area is processed according to the selection of the user when the user watches the video file, so that the watching experience of the user is improved, and meanwhile, the risk of modifying the original video file is reduced.
In the embodiment of the present invention, in the process of playing the target video, the electronic device may identify each first object in the video screen, then determine a target object in each first object, then may acquire the target picture in the album application, identify each second object in the target picture, and generate and display a thumbnail of the first object existing in each second object when it is determined that the first object exists in each second object, and then the user may select a target thumbnail from each thumbnail, and the electronic device may determine the first object corresponding to the target thumbnail as the target object that may be interested by the user. Furthermore, the electronic device may mark the picture area where the target object is located in the target video playing process, and then, the electronic device may receive a first input from a user, and in response to the first input, may control the picture area where the target object is located to zoom and/or move. In the embodiment of the invention, the electronic equipment can screen out the objects which are possibly interested by the user in advance according to the pictures applied to the photo album, so that the efficiency of the user for selecting the focused object is improved, and the intelligent personalized recommendation is realized because the thumbnails of the same target video are different on the electronic equipment of different users. In addition, the electronic equipment can mark the picture area where the specific object is located in the video playing process, and can control the picture area where the specific object is located to zoom and/or move according to the user requirements, so that the user can focus on the specific object while watching the video without pausing the video for screenshot viewing, the operation of observing the specific object in the video is simplified, and the efficiency of focusing on the specific object is improved. In addition, because the video pictures do not need to be converted into pictures, the continuity of the context of the video pictures can be kept while paying attention to specific objects, and the user experience is improved.
