Review of Dim Small Target Detection Algorithms in Single-frame Infrared Images

With the development of infrared detection technology and its independence from environmental, time and other factors, the application in space-based early warning, missile guidance and more and more, infrared small target detection technology has gradually become the focus of research on detection technology at home and abroad. Analyze the characteristics of images containing small infrared targets, review the current single-frame infrared image dim small target detection algorithms based on three types of algorithms: filtering, HVS, and image data structure, and finally provide an outlook on the detection technology.
