The research of pseudo-color infrared and visible light image fusion detection methods of dim and small target based on visual attention

Infrared and visible images have their own characteristics and different imaging principles, the targets be detected by any kind of sensor have their own advantages and disadvantages. In this paper, the characteristics of infrared and visible light images in dim and small target detection are analyzed, and pseudo-color infrared and visible light image fusion detection methods of dim and small target based on visual attention is studied, and its fusion detection effect is analyzed. The research shows that the fusion algorithm in this paper is more effective for targets with complex background and low contrast, and this method only makes pseudo-color mapping on a local area of the target, which is not easy to cause visual fatigue.
