Single color image dehazing based on digital total variation filter with color transfer

For the color fadedness and the contrast reduction of hazy images, we propose a novel method based on digital total variation (TV) filter with color transfer (DTVFCT) for single color image dehazing. The estimation of atmospheric veil is a filtering problem on the minimal component image and the digital TV filter is applied to preserve the edges and gradients of images to avoid halo artifacts. To obtain a quality vision of a resulting image, color transfer is utilized to protect the final haze-free image´s color from high dynamic. The proposed method enjoys a celerity because of fast convergence of digital TV filter. The experiment results show the vivid color and the accuracy of the restored edges and gradients in the comparative study.
