Embodiment Construction

[0145] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0146] In order to solve the problem in the prior art that when the video is a long video or a video with a fast scene switching frequency, the number of sub-video segments that need to be divided increases, resulting in a large amount of calculation in video segmentation, feature extraction and similarity judgment. The embodiment of the invention provides video matching, retrieval, classification and recommendation methods, devices and electronic equipment.

[0147] The video matching, retrieval, classification and recommendation methods provided by the embodiments of the present invention are all implemented based on the density clustering algorithm.

[0148] For the sake of clarity, first introduce the density clustering algorithm and the related definitions involved:

Abstract

The embodiment of the invention provides a video matching, retrieving, classifying and recommending method and device and an electronic device. The video matching method includes the steps of acquiring a to-be-matched video; extracting a plurality of key frames from the to-be-matched video; extracting an image feature value of each key frame of the to-be-matched video; using a density clustering algorithm for selecting a key frame in line with preset conditions from the key frames of the to-be-matched video according to the image feature value of each key frame as a core scene frame to be matched; comparing the similarity between the core scene frame to be matched with pre-stored core scene frames of each original video; if any one core scene frame of an original video is similar to the core scene frame to be matched, determining the original video as a target video which is matched with the to-be-matched video. According to the embodiment, the problem of large computational amount dueto too many long video frames and frequent scene switching is solved.

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...
