Abstract

The invention provides a video cover extraction method and device, equipment and a computer readable storage medium, and relates to the artificial intelligence field. The method comprises: performing image feature extraction on a video frame sequence of a to-be-processed video to obtain a visual feature vector corresponding to the video frame sequence; performing word vector feature extraction on the video text information of the to-be-processed video to obtain a text feature vector corresponding to the video text information; performing feature fusion on the visual feature vector and the text feature vector to obtain a multi-modal fusion feature corresponding to the to-be-processed video; and selecting a video cover frame of the to-be-processed video from the video frame sequence based on the multi-modal fusion feature. According to the invention, the accuracy of video cover extraction can be improved.

Description

technical field [0001] The present application relates to artificial intelligence technology, and in particular to a video cover extraction method, device, equipment and computer-readable storage medium. Background technique [0002] At present, most of the technologies for selecting video covers are to extract image modality information, such as visual feature information, from the video frame images, and then select the video cover from the video frame images based on the extracted visual feature information. This method of selecting a video cover through image modality information uses relatively single information dimensions, and the selected video cover cannot well represent the information in the video content, and the accuracy is low. Contents of the invention [0003] Embodiments of the present application provide a video cover extraction method, device, and computer-readable storage medium, which can improve the accuracy of video cover extraction. [0004] The te...
