Color transfer is a way to get the night vision image with natural col or.The color transfer to low-light level and infrared fused image based on an i mproved Retinex image enhancement is studied in this paper.First,the gray-level fusion of low-light level and infrared images is made employing the pixel averaging fusion scheme,then the fusion image of brightness and contrast is enhanced using the improved multi-sc ale retinex algorithm, and at last color transfer to the enhanced fusion image is conducted based on matching neighborhood brightness- contrast of the color image as reference in YCbCr color space.Experimental resul ts show that the fusion image′s detail is significantly improved after multi-scale Retinex enhancement,the matching a ccuracy is improved, which leads to the misinformation reduced due to the close brightness between ta rget and reference images in the traditional algorithm,and the fusion image is with natural color similar to th e reference one.
