Color transfer is a way to get night vision with natural color. For infrared and low-light level image,a color fusion method of night vision image based on color transfer and target enhancement is presented. Firstly,considering the characteristics of infrared and low-light level images,TNO method is used to get a pseudo-color image (target image),which preserves the details of the image. Then,a similar reference image is selected,and the target image and reference image are converted to the YCbCr color space,and each of the channel′s mean and standard deviation is matched to complete color transfer. Meanwhile,a contrast enhancement factor is introduced into Cr channel to enhance the target. The experimental results show that the method can get a night-vision images with a nature color appearance and improve image detail,and the goal is more highlighted,which helps for understanding the scene.
