In order to solve the visual discontinuous phenomenon that produced by TV method, improve the effect of image restoration,adopts a histogram equalization (CLAHE) operation which can strengthen the details and expand dynamic range of the image. After the TV transformation,uses a morphology operation to smooth and eliminate isolated points of the image. This paper presents the algorithm principle and implementation steps,the experimental results show that,after repair,the whole image has a better visual repairing effect and a high PSNR.
