Embodiment Construction

[0064] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0065] like figure 1 As shown, the implementation steps of the present invention are as follows:

[0066] It is preferred to give a video sequence, give the position and size of the tracking target of the t-th frame, and then determine the target search area and extract features;

[0067] Then, in the target search area, the spatial perception weight map P and the color histogram-based target similarity weight map T are calculated respectively, and the weight map W of the t-th frame is obtained. t ;

[0068] Based on the obtained weight map W of the t-th frame t , the correlation filter of the t-th frame is trained;

[0069] According to the trained correlation filter of the t-th frame, the target response map of the t+1-th frame is calculated, and the target position of the t+1-th frame is calculated.

[0070] Find a high-confidence APSR strategy ...

Abstract

The invention relates to a correlation filtering target tracking method for occlusion, which comprises the following steps of: step 1, for a section of tracked video sequence, giving the position andsize of a tracking target of a t-th frame, determining a search area, calculating characteristics, and calculating a weight map of the t-th frame; step 2, based on the obtained weight graph of the t frame, training a related filter of the t frame; step 3, calculating a target response graph of the (t + 1) th frame according to the trained related filter, and calculating a target position of the (t + 1) th frame; and step 4, on the basis of the (t + 1) th frame target position, obtaining a high-confidence APSR strategy, and determining whether the related filter of the t th frameis updated or not.

Description

technical field [0001] The invention relates to a correlation filtering target tracking method for occlusion, belonging to the fields of pattern recognition and computer vision. Background technique [0002] With the increasing development of computer vision, visual tracking has been widely used in many computer vision tasks, such as video surveillance, human-computer interaction, and unmanned perception systems. Given the true location of the object in the first frame, the tracker can locate the object of interest throughout the video sequence. Although visual tracking methods have made great progress, there are still many challenges, such as deformation, occlusion, out-of-view, scale change, in-plane rotation, etc. [1]. [0003] In recent years, discriminative class tracking methods have attracted great attention. The discriminative approach treats object tracking as a binary classification, i.e. the object and the background region in the video. Many discriminative met...
