[0026] Figure 1 FIG. 1 is a flow chart of a video processing method according to an embodiment of the present disclosure. Figure 1 As shown, the video processing method includes the following steps S11 to S14.

[0027] In step S11, a video to be processed is obtained.

[0028] In step S12, the object to be processed is detected from the video to be processed.

[0029] In some embodiments, the music card points of the video to be processed may be detected first; then, based on the music card points, key frames may be obtained from the video to be processed; then, the object to be processed may be detected on the key frames. For example, the video frame at the location of the music card points may be determined as a key frame, and the object to be processed may be detected from the key frame.

[0030] In some embodiments, a key frame containing a salient object in the video to be processed may be first obtained, and then the salient object may be obtained from the key frame as the object to be processed.

[0031] In addition, it should be noted that, in the present disclosure, the music card points of the video to be processed may be detected first, and then the video frame at the position of the music card point is determined as a key frame, and then the key frame is detected to see whether it contains a significant object. If the key frame contains a significant object, the significant object is obtained from the key frame as the object to be processed. While obtaining the object to be processed based on the music card points, the significant object may also be detected in other video frames other than the music card points as the object to be processed.

[0032] In step S13, the edge of the object to be processed is determined.

[0033] In some embodiments, the edge in the key frame may be first obtained, and then the mask of the object to be processed may be obtained, and then the edge of the object to be processed may be determined based on the edge in the key frame and the mask. For example, the edges of all objects included in the key frame may be determined first, and then the mask of the object to be processed may be obtained, and then the edge of the object to be processed may be obtained from the edges of all objects included in the key frame based on the mask of the object to be processed.

[0034] In step S14, edge lines are added to the edge of the object to be processed to process the video to be processed and obtain the target video. For example, color strokes, straight line strokes, vintage shredded paper strokes, process strokes, etc. can be performed on the edge of the object to be processed. Process strokes can, for example, be adding edge lines to multiple edges of the object to be processed in sequence.

[0035] In some embodiments, the edge of the object to be processed may be superimposed with a texture and / or the contour attributes may be adjusted to obtain the edge line, and then the edge line may be added in a preset appearance manner at the position of the edge of the object to be processed to obtain the target video. The texture may include features such as color and grayscale. The contour attributes may include features such as the thickness and shape of the edge of the object to be processed.

[0036] The preset appearance mode may include at least one of the following: (1) making the edge lines appear in sequence from top to bottom; (2) making the edge lines appear in sequence from left to right; (3) making the edge lines appear in an enlarged manner; (4) making the edge lines appear in a reduced manner; (5) every N frames, controlling the edge lines to be deformed at the position of the edge of the object to be processed to add edge lines, for example, the deformation can be performed at a preset speed curve.

[0037] For example, for the edge lines of retro shredded paper strokes, the outer contour edge of the object to be processed can be detected once every N frames, and the edge lines of the retro shredded paper strokes can be deformed to different degrees in frames other than the first frame of these N frames, such as expanding outward, and the expansion step size can be a preset speed curve.

[0038] By adopting the above technical solution, since it is possible to detect the object to be processed from the video to be processed, determine the edge of the object to be processed, and add an edge line to the edge, the video to be processed is processed to obtain the target video, thereby being able to simply and efficiently add colorful graffiti effects to the videos shot by users, thereby increasing the interest of the videos.
