Method for enhancing image edge

摘要

Disclosed is a method for enhancing an image edge. An edge filter is applied to a photographed image, and the determination is performed with respect to whether pixels having edge possibility are noise or form an edge. The determination for the noise and the edge is performed once more with respect to pixels having vagueness for the noise and the edge by using a 3×3 mask. An edge enhancement process is performed through a simple algorithm.
