Embodiment Construction

[0040] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0041] see figure 2 As shown, a preferred embodiment of the present invention is based on an integrated infrared target detection and tracking algorithm of extension immunity, including an infrared target detection module and an infrared target tracking module, which include:

[0042] S1. Read in the first frame image of the infrared video sequence, generate an image grayscale training set, divide the image into two parts according to the inter-class variance of the image grayscale, and use the ViBe algorithm for the initial immune segmentation. The ViBe algorithm is based on multiple frames. The immune initial segmentation method of infrared images establishes a background model through the previous N frames of images, and judges th...

Abstract

The invention belongs to the technical field of image processing, and particularly relates to an infrared target detection and tracking integrated algorithm based on extension immunity. In the algorithm, a negative selection algorithm and a KCF tracking algorithm are improved by applying an extension theory, an infrared target detection module and a tracking module are redesigned, and target center position information of the detection module is sent to the tracking module, so that integration of infrared target detection and tracking is realized.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an integrated algorithm of infrared target detection and tracking based on extension immunity. Background technique [0002] Infrared target detection and tracking technology plays an important role in the fields of intelligent security monitoring, criminal investigation scene survey, military combat strike, fire search and positioning, etc. However, in practical applications, due to the limitations of the infrared image acquisition system and the ambient temperature, infrared target detection and tracking face many difficulties. In terms of infrared target tracking, there are problems such as target loss, target occlusion, and changes in target shape and size that cause tracking misjudgment. In response to the above problems, researchers at home and abroad have proposed a variety of algorithms. Representative algorithms include the method of local intensit...
