| Abstract: | In order to improve the image edge detection accuracy and noise performance,this paper proposes an image edge detection algorithm based on ant colony optimization.The value of pixel gradient and the relative difference of statistical means of the pixel's circle neighborhood are combined to be the heuristic information which can guide ant's searching.Experimental results show that the edge detected by the proposed algorithm is robust to noise and texture,and contains most of the edge details. |
