Title:
VIDEO RETRIEVAL METHOD, AND METHOD AND APPARATUS FOR GENERATING VIDEO RETRIEVAL MAPPING RELATIONSHIP
Document Type and Number:
WIPO Patent Application WO/2019/219083
Kind Code:
A1
Abstract:
The present disclosure relates to a video retrieval method, a method, system and device for generating a video retrieval mapping relationship, and a storage medium. The video retrieval method comprises: acquiring a retrieval instruction, wherein the retrieval instruction carries retrieval information for retrieving a target frame picture; and obtaining the target frame picture according to the retrieval information and a preset mapping relationship. The method for generating a video retrieval mapping relationship comprises: performing a feature extraction operation on each frame picture in a video stream by using a feature extraction model so as to obtain a key feature sequence corresponding to each frame picture; inputting the key feature sequence corresponding to each frame picture into a text sequence extraction model for processing so as to obtain a text description sequence corresponding to each frame picture; and constructing a mapping relationship according to the text description sequence corresponding to each frame picture. By means of the video retrieval method and the method for generating a video retrieval mapping relationship provided in the present application, the efficiency of video retrieval can be improved, and human-machine interaction is made more intelligent.
