Abstract :
A gray image of natural texture satisfies the model of fractional Brownian random field. The limitation of available methods for edge detection based on fractal characteristics is analyzed and a novel method is proposed. The lacunarity, which is a high-order fractal feature and another fractal parameter (II value) are extracted for detection. With the new method, the experiments show that the edges of gray images can be obtained clearly and completely
