Abstract

The invention relates to an infrared target detection method, equipment and a medium. The method comprises the steps that superpixel partitioning is performed on an infrared image to obtain a first image, and boundary superpixel features of the first image are extracted to serve as a background sample set; dense error reconstruction is performed on the background sample set to obtain a backgroundsaliency map; an undirected graph model based on the infrared image is constructed, and sparse features of the undirected graph model are extracted to obtain a target saliency map; and a Bayesian formula is utilized to fuse the background saliency map and the target saliency map to obtain an infrared target. Through the infrared target detection method, the equipment and the medium, on the basis of performing superpixel partitioning on the infrared image, the sparse features are extracted through the undirected graph model, a salient region is highlighted more accurately, and the accuracy of adetection result is further improved in combination with the dense error reconstruction method.

Description

technical field [0001] The invention relates to a method in the technical field of image processing, in particular to an infrared target detection method, equipment and medium. Background technique [0002] Infrared target detection is the core technology of infrared signal processing, which is applied in many fields such as infrared search and track (IRST) system, precision guidance system, target monitoring system, and satellite remote sensing system. In recent years, intelligent information processing methods based on visual attention mechanism have become a major research hotspot. The saliency analysis method is widely used in the field of infrared object detection due to its fast localization ability. [0003] The saliency analysis method combines image features and orientation information measures to reduce the target search range. It is widely used in many civilian and military applications, such as image segmentation, image detection, object recognition, video trac...
