Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] At first introduce several technologies related to the present invention:

[0054] Correlation filter tracking: The idea of ​​correlation filter application in tracking: the more similar two signals are, the higher their correlation value will be. Correlation filtering is applied to tracking, which means that a filtering template needs to be obtained, and when it acts on the tracking target, the response obtained is the largest.

[0055] HOG feature: H...

Abstract

The invention belongs to the technical field of computer vision, and discloses a video target tracking method. According to the invention, fused HOG and LBP features are used as the input of relative filtering tracking. Compared with traditional and pure gray value and HOG features, the fused feature can better describe a target. The HOG features are used to better describe the edge and other features of an image. The LBP features are used to better describe the texture features of the image. The noise impact is overcome. The combination of HOG and LBP features can make tracking more stable.

Description

technical field [0001] The invention belongs to the technical field of computer vision, and in particular relates to a video target tracking method. Background technique [0002] Visual object tracking is an important research field in computer vision, which involves pattern recognition, image processing, artificial intelligence and many other aspects of knowledge. It is widely used in many fields such as intelligent surveillance, video coding, traffic control and military target guidance. In recent years, target tracking technology has been a hot research topic, and some new methods and theories are constantly emerging. Nevertheless, visual target tracking still faces some inherent problems, such as illumination changes, target scale changes, noise interference, real-time performance and accuracy of tracking, etc. [0003] Researchers from various countries are researching and improving visual tracking from different angles, and the methods of target tracking are also con...
