Morphological edge-enhancing filtering of images

摘要

Abstract: The application of mathematical morphology to edge enhancement of images is studied in this paper, and a morphological edge enhancing operator and its anti-noises counterpart are also presented. This morphological operator enhances the gradients of edges while attenuates noises and preserves edges. It is showed by computer simulations that the gradient of edges is enhanced by the morphological edge enhancing operator and, then, the structure and feature of images are strengthened and edges can be easily extracted.!8
