摘要：In this paper, adaptive Perona-Malik (PM) diffusion method is introduced which combines both the PM equation as well as the heat equation. The advantages of the PM equation are image segmentation, image enhancement, noise removal, edge detection, etc. The edge indicator is used as a variable exponent as a result of which, the diffusion mode can be controlled adaptively. The enhancement method is done by using adaptive linear filtering technique for image restoration. This method is adopted for enhancing the resolution, restoration of image pixels and for improving the quality of ultrasound images and magnetic resonant images.
