Abstract

The invention relates to a video browsing method and device and belongs to the technical field of computers. The video browsing method comprises the steps that a current image frame in a video is compared with a previous image frame in the video, and target block information is obtained; if the target block information meets a preset condition, the current image frame is determined as a key frame; the next image frame of the current image frame is determined as a current image frame, the step that the current image frame in the video is compared with the previous image frame in the video to obtain target block information is conducted continually and not stopped until the last image frame in the video is compared; at least one determined image frame is played. The device comprises an image comparing module, an image determining module, an operation executing module and an image playing module. The video browsing method and device solve the problem that the video cannot be browsed due to the fact that the key frames cannot be extracted from the video with sequences, and the effect of improving the playing efficiency of the video is achieved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a video browsing method and device. Background technique [0002] With the development of the Internet, online video is used more and more frequently. When we obtain a video, we need to quickly browse the video to understand the content of the video. Therefore, how to quickly browse the video has become a problem that people pay attention to. [0003] Since the video is composed of continuous image frames, in the process of extracting key frames of the video, the terminal will segment the video into at least two shots; according to the boundary of each shot, respond to changes in image quality and video content Select a set of keyframes for each shot; these keyframes are reproduced on screen at the appropriate rate for video browsing. [0004] During the process of implementing the present disclosure, the discloser found at least the following defects in related tech...
