Similar video retrieval method and system based on Lucene

Abstract

The invention provides a similar video retrieval method based on Lucene. The similar video retrieval method comprises the steps that S1, a Lucene video indexing library is established at different nodes of a cluster respectively; S2, sample videos for retrieving similar videos are obtained, and meanwhile retrieval is performed in each Lucene video indexing library to obtain result videos similar to the sample videos respectively; S3, the result videos of all the nodes are collected, arrangement is performed according to similarity coefficients to form a result video set, and the result video set is output. The invention further provides a corresponding system. By implementing the method, the nodes perform retrieval simultaneously during retrieval, the retrieval speed is improved, and the retrieval quality is ensured. In addition, by using the Lucene as a retrieval engine and using a cosine similarity algorithm to calculate video similarity, the comparison speed is accelerated, meanwhile the preprocessing time in the video retrieval process is shortened by pre-establishing the Lucene video indexing libraries, extracted video frames are compressed to decrease the calculation quantity for frame comparison, and the comparison speed is further improved.

Description

technical field [0001] The present invention relates to the technical field of computer internet, and more specifically, relates to a method and system for searching similar videos based on Lucene. Background technique [0002] Video content is different from text content, and video cannot be retrieved like text retrieval, but in real life, especially on the Internet, there is a strong demand for video content retrieval. [0003] In the prior art, there have been some methods and devices for retrieving video content. However, the work done on video retrieval basically focuses on how to analyze the frame features in the video, and the retrieval speed has not reached Ideal effect, but the speed is slow, and the retrieval process is time-consuming. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a Lucene-based similar video retrieval method and system for the problem that the retrieval speed of video retrieval in t...
