Abstract

The present invention provides a content-based video retrieval method, comprising: receiving a video search request via a human-computer interaction interface; triggering a plurality of retrieval processes according to the video search request, including: triggering a metadata retrieval server to retrieve the metadata of a video program Retrieve; trigger the subtitle retrieval server to retrieve the XML file storing the subtitle text of the program; trigger the video retrieval cluster to retrieve the feature data of video key frames; trigger the voice retrieval cluster to search the voice information of the video program, including pinyin strings and pinyin diagrams Retrieve; integrate each search result, and then return it to the user through the human-computer interaction interface. This method provides an efficient solution for content-based video retrieval.

Description

technical field [0001] The present invention relates to the field of content-based video retrieval (CBR). Including the organization and storage of video feature data, the indexing and retrieval of high-dimensional feature vectors, distributed retrieval and other technologies. Background technique [0002] An information retrieval system usually includes a core retrieval database, a search scheduling server and server groups. Externally, it provides an interface for searching and information entry. Such as figure 1 shown. [0003] Among them, information entry mostly relies on manual typing. That is, the provider of the retrieval content in the system enters the content information provided to the user and used for searching into the database through the information entry interface of the retrieval system. [0004] The core database system is mainly responsible for storing information data for user retrieval. [0005] The search scheduling server is responsible for rec...
