Embodiment Construction

[0024] As shown in FIG. 1 , the present invention mainly includes a video stream acquisition module, a video content analysis module, a video content analysis result review module, an input interface, an output interface, a task scheduling module and a user interface.

[0025] The system receives video analysis commands through the input interface, and there are two receiving methods: receiving video analysis commands from the video fusion analysis server through the network TCP connection and obtaining the user's video analysis commands locally. The video fusion analysis server is an overall scheduling server for video analysis, and is used for distributing video analysis instructions. Contain the various information of the video file that needs to analyze in the command, comprise video analysis task ID (referred to as PID in the present invention), priority (comprising high, common and low three levels), task basic information (screen length, screen Width, frame rate), basic...

Abstract

This invention relates to a video content analysis system including: an input interface, a task dispatch module, a video stream obtaining module, a video content analysis module, a check module for video analysis result, an output interface and a UI. The system flow includes: the system receives the video analysis instruction from the network or the local, the task dispatch module decides the execution sequence of the task, the video flow obtaining module decodes the being analyzed video and the content analysis module analyzes and picks up lens information, the lens key frame information, the scene information, key frame information, its image information and man-face informatioin to be checked according to the need to be stored in the mode of XML file to be uploaded to the video information database via the output interface, and the system is used in supporting video search service based on content.

Description

technical field [0001] The invention belongs to the technical field of video analysis and retrieval, and in particular relates to a video content analysis system. Background technique [0002] In this era of knowledge explosion, with the widespread use of the Internet and the continuous expansion of the storage capacity of database systems, people are faced with more and more video data, and the application of video information is also becoming more and more extensive. The demand for video retrieval is becoming more and more urgent. . [0003] The traditional video retrieval system includes a video information database system to store video related information. These video information often only contain video metadata information manually input, and the information form is single and the amount of information is small, which is difficult to meet the retrieval needs of users. [0004] In order to change the situation of video data retrieval, it is necessary to order the unor...
