Embodiment Construction

[0024] A video content retrieval method based on moving objects, the method includes the following sequential steps: (1) Obtain the initial image sequence of all video files in the video library, analyze and process the initial image sequence, obtain the position of each moving object, and calculate The visual statistical features of each moving target, and store the position and visual statistical feature information of each moving target in the video index database; (2) The user inputs the object to be retrieved, selects the moving target to be retrieved from it, and calculates the motion to be retrieved (3) Find the video index record most similar to the moving target to be retrieved in the video index database; (4) Select the corresponding video segment from the video library according to the retrieved video index record, and displayed on the user monitoring terminal. like figure 1 shown.

[0025] The object to be retrieved is an image or a video clip to be retrieved. I...

Abstract

The invention relates to a video content retrieval method based on moving objects. The method comprises the following steps of: analyzing and processing initial image sequences of all video files in a video library to obtain the positions of the moving objects, calculating the visual statistical characteristics of the moving objects, and storing the visual statistical characteristics in a video index database; inputting objects to be retrieved by a user, selecting moving objects to be retrieved from the objects, and calculating the visual statistical characteristics of the moving objects to be retrieved; looking up the video index record most similar to the moving objects to be retrieved; and selecting and displaying the corresponding video segment from the video library according to the retrieved video index record. The invention also discloses a video content retrieval system based on the moving objects. According to the invention, by detecting and tracking the moving objects in all video files in the video library,,automatic retrieving can be rapidly carried out on the video contents, thus the high efficiency of video content retrieval is improved, and the adaptability of the video retrieval system is improved.

Description

technical field [0001] The invention relates to the field of video content retrieval, in particular to a video content retrieval method and system based on moving objects. [0002] Background technique [0003] With the development of economy and information technology, people's demand for safety precautions is getting higher and higher. As an effective means in the field of safety prevention, video surveillance has a wider and wider range of applications, and the application requirements are constantly improving. [0004] In daily applications, a large number of video files are generated every day, and how to find content of interest to users from these video files has become a difficult problem. It is extremely time-consuming and labor-intensive to search manually, especially when the number of videos is increasing rapidly, this method is becoming increasingly unfeasible. Therefore, the use of information technology to automatically retrieve video content research has be...
