METHODS OF ANISOTROPIC DIFFUSION AND FOVEAL SEGMENTATION OF DIGITAL IMAGES

摘要

Image processing method, particularly suitable for processing noisy images such as digitised mammograms. An adaptive anisotropic diffusion processing method is described in which the diffusion parameter is adjusted in accordance with the contrast in the image. An adaptive foveal segmentation method is also described in which the segmentation parameters are set adaptively in accordance with the contrast in the image.
