Abstract

The embodiment of the invention discloses a video cropping method and device, and the method comprises the steps: obtaining a to-be-processed target video, and recognizing the position of a target object from a video frame of the target video; determining a motion track of the target object in the target video according to the identified position of the target object; based on the determined motion trail, cutting out a region image containing the target object from a video frame of the target video; and making a clipped video corresponding to the target object according to the cropped region image. According to the technical scheme provided by the invention, the cropped video can still display the main content of the original video.

Description

technical field [0001] The present application relates to the technical field of video processing, and in particular to a video clipping method and device. Background technique [0002] At present, videos played on mobile terminals usually have two versions, a horizontal version and a vertical version. Due to the large difference in resolution between the horizontal and vertical versions, it is difficult for the same video to meet the playback requirements of both the horizontal and vertical versions. [0003] At present, in order to make the horizontal version of the video have a better viewing experience in the vertical version of the scene, it is usually selected to intercept a part of the picture from the horizontal version of the video, so as to make a corresponding vertical version of the video. Currently, when making a vertical video based on a horizontal video, some information in the horizontal video will inevitably be removed. see figure 1 , in the prior art, us...
