Removing noise effectively without destroying important fine structure is a challenging problem in image processing. Among many techniques, diffusion method is shown to be attractive due to its rigorous mathematical background and efficiency. In this paper we propose a well-balanced diffusion method by redefining the diffusion and regularization function. Results obtained from processing synthetic and real images demon- strate that our new method can obtain better performance in terms of removing noises without destroying detailed features of images.
