Abstract

The present application provides a method and device for determining the segmentation of teaching videos. The foregoing method includes: extracting frame images of teaching videos according to the first cycle to form an ordered image set; comparing the adjacent images in the ordered image set. frame image, determine a temporary segmentation point; determine the first frame image and the second frame image according to the temporary segmentation point; compare the first frame image and the blackboard area of ​​the second frame image, and determine the first similarity ; The first frame image is a frame image before the temporary segmentation point, and the second frame image is a frame image after the temporary segmentation point; according to the first similarity, the corresponding Temporary segmentation point: use the remaining temporary segmentation point as the actual segmentation point of the teaching video. The content of the blackboard writing area is directly related to the teaching theme, so the content of the blackboard writing area can be used to more accurately screen the temporary segmentation points, and then realize the segmentation of teaching videos according to the content characteristics of teaching videos.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular to a method and device for determining the segmentation of teaching videos. Background technique [0002] In order to quickly locate a specific content area in a video and meet the needs of quick search and specific content extraction, there are currently methods for content identification of film and television and documentary videos based on video content to determine segmentation. [0003] The method of identifying the index points for film and television and documentary videos is mainly based on the fact that such videos have scene change characteristics, and the scenes before and after the change have significantly different characteristics, and the segmentation index is determined by using the large-scale changes of the image frame. [0004] Because the teaching video has the feature that the scene characteristics basically do not change, the above-mentioned...
