Embodiment Construction

[0083] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0084] The present invention provides a single target tracking method, such as Figure 5 As shown, it is assumed that the video V={F consisting of N frames of grayscale pedestrian images is known 0 , F 1 ,…F N}, the width and height of the frame image are w, h respectively, including the following steps:

[0085] The first step, get parameters

[0086] Such as Figure 5 As shown in ①, the specific initialization steps are as follows:

[0087] 1) By manual, in F 0 Get target O in frame 0 Rectangular box B at initial position 0 =[x 0 ,y 0 ,w 0 ,h 0 ], where x 0 ,y 0 ,w 0 ,h 0 Respect...

Abstract

Provided are a single target tracking method and an achievement device thereof. The single target tracking method includes that in a video V (V={F0, F1, FN}) formed by N frames of gray level images, a target O0 is selected in an F0 frame, and the image O0 is subjected to graying and width and height normalization processing to obtain an initialized parameter of the image; classifier initializing and updating which include training set constructing, feature extracting and model updating are carried out; and target tracking is carried out on the Ft+1 frame of image through an ft+1 model. The single target tracking method displays target surface appearances in a binary feature based compressed sensing and dimension descending method, can effectively display target deformation, improves shielding resistance and light resistance, and accordingly can achieve robust target tracking; and meanwhile has the advantages of small memory consumption and calculated amount, and achieves real-time tracking speed.

Description

technical field [0001] The invention relates to a tracking method for a given target starting position and a device for realizing it, in particular to a method for tracking a single target and a device for realizing it. Background technique [0002] The research on tracking technology based on the characteristics of moving objects is a hot topic in the field of computer vision in recent years. Although biometrics such as fingerprints, palmprints, and veins have been extensively researched and initially applied in the security field, these biometrics belong to contact recognition, which greatly limits their application range. Relatively speaking, the "non-contact" recognition technology such as gait and face recognition, which combines human motion and biological characteristics for recognition research, has now become an important field in intelligent scene video surveillance. Especially for gait recognition, it is necessary to collect the characteristics of the moving huma...
