Abstract

The invention discloses a retrieval-oriented monitoring video semantic description and inspection modeling method. The method comprises the steps as follows: first analyzing the advantages and disadvantages of a present MPEG-7 based video description scheme in a monitoring field, and subdividing video objects into moving objects and stationary regions for description, aiming at the problem that user interested stationary regions are not defined. The method simultaneously defines a second-stage spatial relationship on a time dimension to describe a time variable spatial relationship, in order to solve the problem of description information redundancy in the relationship between objects in a description flow. At last, the method proves that the improved monitoring video semantic description scheme attains a description flow of monitoring video through inspection modeling of events, and can well support the understanding of high-level semantic information.

Description

technical field

[0001] The invention relates to the field of description and retrieval of surveillance video, in particular to an improved semantic description and retrieval method for surveillance video. Background technique

[0002] The 21st century is an information age. With the rapid development of the information technology industry represented by multimedia, people's requirements for the safety of living and working environments are also increasing, and monitoring facilities are increasingly appearing in various public places. At present, video surveillance systems have been involved in all walks of life in society, such as traffic intersections, supermarkets, banks, stations, and residential quarters. Many monitoring equipment, such as Olympic venues, People's Square, World Expo site, etc.
