Abstract

The invention discloses a feature encoder training method. The method comprises the following steps: obtaining a to-be-processed video; selecting two video clips from at least one video to be processed, wherein the two video clips at least partially coincide on a time axis; the two video clips comprise a first video clip and a second video clip; performing image editing processing on the second video clip by adopting a preset image editing mode to obtain an edited second target video clip similar to the second video clip; inputting all frames contained in the first video clip and the second target video clip into a frame feature encoder to obtain a frame feature vector; and training a frame feature encoder according to the frame feature vector to obtain a target frame feature encoder. By the adoption of the method, the problems that in the prior art, a feature encoder is not high enough in robustness to a complex image editing mode, and retrieval performance is limited are solved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a feature encoder training method, device, electronic equipment and storage equipment. The present application also relates to a same-source video query method and a same-source video query device. The present application also relates to a feature encoder training system. Background technique [0002] Currently on the Internet, video files are often copied and shared, and there may be a large number of plagiarized / copied video clips. In order to perform copyright protection on video files, it is necessary to determine which video files or video clips are infringing. When retrieving plagiarized / copied video segments of the query video in the video to be retrieved, video fingerprint (ie feature vectors of video files or video segments) technology is usually used. Video fingerprinting is an emerging video identification technology that can generate a unique "fingerpri...
