Abstract

This specification discloses a video matching method, a blockchain-based infringement proof storage method and a device, the blockchain-based infringement proof storage method includes: obtaining multiple feature vectors of the target video; multiple feature vectors based on the target video A feature vector, from the video database, retrieves a candidate video similar to the target video; based on the target video and the candidate video, constructs a temporal similarity matrix feature map between the target video and the candidate video ;Using the time domain similarity matrix feature map as the input of the deep learning detection model, to output video clips and corresponding similarities matched with the target video in the candidate video; when the similarity is greater than or equal to preset When the similarity threshold is reached, the summary of the target video, the video segments matching the target video in the candidate video and the corresponding similarity infringement evidence are uploaded to the block chain.

Description

technical field [0001] This document relates to the field of computer technology, in particular to a video matching method, a blockchain-based infringement proof storage method and device. Background technique [0002] At present, when locating the infringement of a certain suspected infringing video, it is usually first to extract various features from the video, and then after searching by a search engine, the matching results of multiple candidate videos matching the video are obtained. For the final infringement positioning of the suspected infringing video, it is also necessary to calculate the similarities between multiple candidate videos and the suspicious infringing video. This requires a highly robust algorithm to deal with mis-matching and missing matching of various features between videos, and to support infringement location of multiple video clips. [0003] However, the existing video matching methods are easily affected by the noise of the feature retrieval ...
