In view of the characteristic of small targets in the sky background,an algorithm used for detection of small targets in the infrared image is presented.In the target of more than 9 points,the traditional image processing based on the 3×3 template does not reach the expected effect.Therefore,this paper uses the middle and top-hat filter to process the infrared image based on the 5×5 and 4×4 template.The design adopts the FPGA.Experiments on real infrared images in the sky background show that the algorithms can detect the small target in the infrared image effectively.

Key words: infrared image recognition;top-hat filter;Robinson filter
