Anti-occlusion correlation filtering tracking method and system/device based on multi-peak response

Abstract

The invention discloses an anti-occlusion correlation filtering tracking method and system / device based on multi-peak response. When a target is occluded, most correlation filtering tracking algorithms generate false tracking, an object which occluds the target is regarded as the target, and then a template is updated, so that a model drifts, and finally the tracking fails. According to the anti-occlusion related filtering tracking method, whether a current frame target is occluded or not is detected firstly, and template updating of the current frame is stopped under the condition that it isjudged that the current frame target is occluded early, so that wrong information cannot be learned, and model drifting is prevented. Secondly, an occlusion processing mechanism is added in the anti-occlusion correlation filtering tracking method, the optimal target position of the current frame is found out, when the target appears again, tracking is still correct, and therefore the accuracy androbustness of the tracking algorithm are further improved.

Description

technical field [0001] The present invention relates to the field of computer vision tracking, and more specifically, to an anti-occlusion correlation filter tracking method and system / device based on multi-peak responses. Background technique [0002] Target tracking algorithm is an important technical means for processing video image information in computer vision, and has a wide range of application scenarios, such as robots, video surveillance, intelligent transportation, etc. In recent decades, researchers have proposed a variety of excellent target tracking algorithms, but target tracking in practical environments still faces a series of challenges. In the process of target tracking, it is necessary to face the challenges of fast moving targets, complex backgrounds, occlusions, lighting changes and other uncertain factors, which often lead to tracking failures and require high robustness of tracking algorithms. [0003] Generally speaking, target tracking can be divid...
