Abstract

The embodiment of the invention discloses a video cropping method and a server. The video cropping method provides a target object in a video, and comprises the steps of determining an object contourof a target object in a current frame of a video; determining a target area in the current frame based on the object contour, and determining an image in the target area as a cut frame of the currentframe, wherein in the video, the first deviation degree between the center coordinate of the target area in the current frame and the center coordinate of the target area in the previous frame is smaller than or equal to a specified deviation degree threshold value, and the proportion of the part of the object contour contained in the target area in the current frame is larger than or equal to a specified proportion; and generating a clipped video corresponding to the video according to the clipped frame determined from the video. According to the technical scheme provided by the embodiment ofthe invention, the jitter phenomenon of the clipped video can be prevented, so that the watching effect of the clipped video is improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a video clipping method and server. Background technique [0002] With the rapid development of Internet technology, for more interesting videos, users often want to cut out a video of the moving track of a certain feature object of interest from this video, for example, cut out a dancer from a hip-hop video. The user's video can bring users a different viewing experience. [0003] However, usually, since the position and size of the feature object in the video are always changing, the motion track of the feature object in the video is jumpy. In this way, it may cause obvious jitter phenomenon in the cropped video. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a video clipping method and server, which can prevent the clipped video from shaking, thereby improving the viewing effect of the clipped video...
