Abstract:

Aiming at the problem that it is difficult to analyze the target and background information in the scene of infrared images and low illumination images independently, an infrared and low illumination image fusion algorithm based on image features is proposed. Firstly, the infrared and low illumination images are processed to optimize their characteristics respectively. Secondly, the non-subsampled shearlet transform is used to decompose them in high and low frequency. Thirdly, the improved Laplace weighted algorithm is used to fuse the low-frequency images. The improved pulse coupled neural network is used to fuse the high-frequency images. Finally, the fused image is obtained by non-subsampled shearlet inverse transform. Experimental results show that the proposed algorithm can effectively fuse infrared and low illumination images, reduce the impact of noise on the fused image, improve the clarity of the fused image, and the contrast of the image is moderate, which is suifable the visual perception effect of human eyes.

Key words: low illumination image, infrared image, non-subsampled shearlet transform, pulse-coupled neural network, image fusion algorithm
