Abstract

The invention discloses a video file retrieval method and apparatus. The method comprises the steps of performing at least one round of sampling on a to-be-retrieved video file; if all sampled video clips in the previous round of sampling are matched unsuccessfully in a preset index library, sliding a frame for performing the next round of sampling, until at least one sampled video clip in a roundof sampling is matched successfully in the preset index library; performing full retrieval on all the video clips of the to-be-retrieved video file in the preset index library; or when the retrievalstill fails after sliding for enough times, indicating that no video file matched with a to-be-retrieved video exists in the index library. According to the method, whether a matched retrieval resultexists in the preset index library or not can be quickly determined, so that the retrieval efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of data retrieval, in particular to a video file retrieval method and device. Background technique [0002] With the development of video network, more and more video files need to be managed and retrieved in the network. Video file retrieval is to find matching video clips from a large number of video resources. Common video file retrieval methods include content-based video retrieval, lens-based video retrieval, etc. However, the retrieval efficiency of current retrieval methods is relatively low. Therefore, how to improve the detection efficiency of video files has become an urgent technical problem to be solved. . Contents of the invention [0003] The object of the present invention is to solve one of the above-mentioned technical problems at least to a certain extent. [0004] For this reason, the first purpose of the present invention is to propose a retrieval method for video files, by performin...
