Example Embodiment

[0031] See figure 1 , figure 2 As an implementable manner, a video image target tracking processing method according to an embodiment of the present invention includes the following steps:

[0032] Step S100: Model the background of the current video image, perform foreground target detection on the foreground in the current video image using the background subtraction method, obtain the foreground blobs in the current video image, determine the tracked target, and extract the tracked target The color histogram of the location of the foreground blob;

[0033] Preferably, as an implementable manner, the step S100 includes the following steps:

[0034] Step S110, read the T frame image in the current video image and use the Gaussian mixture model to model the background to distinguish the foreground and background of the image;

[0035] Among them, T is an integer.

[0036] As an implementable manner, in the step S110, modeling the background using the Gaussian mixture model to distingu...

Abstract

The invention provides a video image target tracking processing method and system. The video image target tracking processing method comprises the following steps: modeling a background of a current video image, conducting foreground target detection on foregrounds in the current video image to obtain a foreground block mass in the current video image, determining tracked objects, extracting a color histogram at the position of the foreground block mass where the tracked objects are located, after the tracked objects are determined, using size information and historical position information of the foreground block mass of the tracked objects of the current video image to conduct initial training on a Kalman predictor corresponding to the tracked objects, updating the color histogram of the tracked objects in the current video image, and tracking the tracked objects in a follow-up continuous video of the current video image according to the number, detected according to the current video image, of the tracked objects. The video image target tracking processing method and system are simple, high in efficiency, high in adaptive capacity and capable of accurately tracking and processing the video objects.

Description

technical field [0001] The invention relates to the technical field of image and video behavior analysis and processing, in particular to a method and system for tracking and processing video image objects. Background technique [0002] Video behavior analysis is a technology to extract the behavior of the target of interest in the video through certain image processing from the video sequence. [0003] With the needs of anti-terrorism, public safety and safe cities in the world, the security field has become a broad application stage for video behavior analysis. However, the current level of intelligence in video surveillance facilities is low, and most of them only record video data for subsequent inquiries. , the current video behavior analysis such as stay detection, running detection, etc. cannot meet the actual needs. [0004] In order to better adapt to the needs of practical applications, people have proposed a variety of video behavior analysis methods, such as par...
