Abstract

The embodiment of the invention provides an expression recognition method, device and equipment for characters in a video and a storage medium, and relates to the technical field of video content analysis. The method comprises the steps: obtaining a plurality of first images from a to-be-processed video; graying the first image to obtain a second image; obtaining a face area on the second image through a face detection model; screening out a third image containing a front face from a plurality of second images according to the face area; obtaining figure information corresponding to a face area of the third image through a face recognition model; and obtaining expression information corresponding to the figure information of the third image through an expression recognition model. The method greatly improves the efficiency of video analysis and video marking in the prior art, is stable and reliable, is not affected by human factors, and has good practical significance.

Description

technical field [0001] The present invention relates to the technical field of video content analysis, in particular to a method, device, device and storage medium for facial expression recognition of characters in a video. Background technique [0002] With the advent of the era of great Internet development, the total amount of video streaming media data continues to expand, and the streaming media market is developing in the direction of integrating resources and optimizing output effects with high quality. Streaming media contains a lot of important information, but the current level of data mining of video streams is only the tip of the iceberg. [0003] Among them, the changes in the expressions of the characters can reflect the overall plot trend of the video. If the video streaming information is fully excavated and effectively marked, it will help the development of video streaming industries such as movies and self-media and bring broad market prospects. In partic...
