Remnant quick detecting method based on history pixel set matching degree

Abstract

The invention discloses a remnant quick detecting method based on history pixel set matching degree. The method comprises the following steps that first, video information is received, namely the video information to be processed collected by video collecting equipment is received; second, a self-adaptive background model is established, namely the first N image data frames in the video information to be processed are respectively processed, the self-adaptive background model used for moving target detecting is established, the self-adaptive background model is a code book model; third, remnants are detected, namely history pixel sets of pixels are established first, and then the established history pixel sets are used for carrying out remnant detecting on image data frames after the Nth image data frame of the video information to be processed respectively. The steps of the method are simple, designing is reasonable, realization is convenient, detecting speed is high, detecting effect is good, and the problems that an existing remnant detecting method is bad in complex scene adaptive capacity, large in calculated amount, and low in detecting speed, and detecting again cannot be easily carried out when blocking and moving happen can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of video surveillance, and in particular relates to a method for quickly detecting remnants based on the matching degree of historical pixel sets. Background technique [0002] As people pay more attention to the safety of public places, more and more public places such as squares, railway stations, and airports have installed video surveillance systems. However, due to the large number of cameras used in video surveillance systems, it is difficult for monitoring personnel to Suspicious behaviors are discovered at the first time, causing incidents that endanger public safety to occur from time to time. Therefore, the intelligent monitoring system came into being and became a research hotspot in recent years. Among them, the remnant object detection is an important part of the intelligent monitoring system, which is used to automatically monitor whether there are suspicious objects in the scene. Remains det...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a rapid detection method for remnants based on the matching degree of historical pixel sets, which has simple steps, reasonable design, convenient implementation, fast detection speed and excellent detection effect. Good, it can effectively solve the problems of poor adaptability to complex scenes, large amount of calculation, slow detection speed, and difficult to be re-detected when occlusion and movement occur in existing relic detection methods.
