Perona and Malik in the heat conduction equation based on an anisotropic diffusion equation and its application to image processing in scale space of image smoothing on the edge of the model for the image part and the non-edge parts of the different types of image processing, also calculate the iterative equation is simple, to overcome the major shortcomings of traditional filtering is much improved image quality for image edge detection and enhancement to open up a new direction.
