Issues on Infrared Dim Small Target Detection and Tracking

Infrared dim small target detection has always been one of the difficulties in the field of infrared image processing. Due to the long imaging distance, targets usually occupy a few pixels in images, and lack of textural information. Besides, there is usually low contrast between the small targets and backgrounds in infrared images, the small targets are easily immersed in complex backgrounds, also raise the difficulty. Infrared dim small target detection and tracking technology is of great significance and high value in military and civilian applications and has broad application prospects. This paper focuses on the typical algorithm principles and characteristics of infrared dim small target detection and tracking technology. On this basis, the research status and development trend of infrared dim small target detection and tracking technology are predicted.
