Abstract

The invention provides a trackability distinguishing method of an infrared sequence image. Infrared image quality features, image gradient features and image texture features are utilized for calculating the single-frame image detectability confidence coefficient of each frame of image in the sequence image, and weighting is carried out to obtain a sequence image detectability confidence coefficient. The invention provides the method for directly calculating the sequence image detectability confidence coefficient by utilizing an image entropy feature and target background feature differences between a front frame and a rear frame in the image. Two methods are both mainly used for infrared target detection and infrared target tracking, and belong to the field of infrared target detection and identification.

Description

technical field [0001] The invention relates to a method for judging the trackability of infrared sequence images, which belongs to the field of infrared target detection and recognition. Background technique [0002] Traceability analysis serves the tracking algorithm, and is used to judge whether the target area is suitable for a certain tracking algorithm. Different tracking algorithms have great differences in performance indicators such as calculation amount and tracking accuracy. At the same time, because the target size, shape, gray level and its distribution, and image resolution in the imaging tracking system can all be affected by environmental conditions Therefore, when the selected tracking algorithm is inappropriate, the tracking results are often poor. At the same time, it is not uncommon for factors such as poor environmental conditions and camera shake to cause poor image quality, which in turn affects tracking performance. [0003] In order to improve the ...
