Video matching, retrieval, classification and recommendation method, device and electronic equipment

Abstract

Embodiments of the present invention provide video matching, retrieval, classification and recommendation methods, devices, and electronic equipment, wherein the video matching method includes: acquiring a video to be matched; extracting a plurality of key frames from the video to be matched; extracting The image feature value of each key frame of the video to be matched; using a density clustering algorithm, according to the image feature value of each key frame, from the multiple key frames of the video to be matched, select the one that meets the preset conditions The key frame is used as the core scene frame to be matched; the core scene frame of the core scene frame to be matched and the core scene frame of each original video stored in advance are similarly judged; if any core scene frame of an original video and the core scene frame to be matched If similar, the original video is determined as the target video matching the video to be matched. The embodiment of the present invention solves the problem of a large amount of calculation caused by too many long video frames and frequent scene switching.

Description

technical field [0001] The invention relates to the technical field of video retrieval, in particular to video matching, retrieval, classification and recommendation methods, devices and electronic equipment. Background technique [0002] With the rapid development of computer technology, network technology and multimedia technology, video data has been widely used in various fields such as entertainment, education and business. Explosive growth. At the same time, there are more and more users watching videos such as movies and TV dramas online, and the demand for video retrieval is increasing day by day. [0003] In the process of video retrieval, classification and recommendation, video similarity matching is required. For example: video retrieval, the main steps include: pre-segment the video for each original video in the video database, obtain multiple video clips, and then extract video features for each video clip, and save each original video. The video characteri...
