Embodiment Construction

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

[0065] Such as figure 1 Shown, the implementation steps of the present invention are as follows:

[0066] Firstly, given a video sequence, the position and size of the tracking target in the tth frame are given, and then the target search area is determined and features are extracted;

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

[0068] Weight map W based on the obtained t-th frame t , train the correlation filter of the tth frame;

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

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

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 aimed at 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 ground-truth position 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] Discriminative class tracking methods have attracted considerable attention in recent years. Discriminative methods treat object tracking as a binary class, i.e. objects and background regions in the video. Many discriminative method...
