Recently, more and more natural image statistics are found useful for image restoration problems. In this paper, we propose a noise reduction technique by use of color-line assumption for natural color images. Based on the color-line model, we propose an algorithm to analyse local color statistics and recover the original image by promoting color linearity of a local patch. Moreover, the proposed method is employed on superpixels to alleviate the boundary effect of the denoising operation. The… CONTINUE READING
