Abstract：Considering the features of SAR image and infrared image ,an image fusion and colorization method based on sparse representation and color transfer is proposed in this paper .Firstly ,the grayscale fused image of SAR image and infra-red image is gained based on sparse representation .Secondly ,the initial color fused image is gained by matching the statistics of target image and the reference image in the YCbCr color space .Finally ,the final color fusion image is obtained by repla-cing the luminance component with the grayscale fused image during the color transfer process .The experimental results show that the proposed algorithm can obtain the perfect contrast and detail information ,and the color of the fusion image is comfortable for human eyes .The situation awareness and target detectability can be enhanced by the method .
