Algorithm for the Detection of FeebSe Edge of Complex Image

摘要

Image weak edge detection has a wide application. An improved ant colony algorithm is used for image edge detection. When image background is very complex ,the weak edge detection is more difficult. Around the key steps in the existing ant colony algorithm, we propose two improved methods. First, the expression of pheromone has been improved, and second, to improve the heuristic information value is calculated. Finally, the improved ant colony algorithm with the traditional Canny edge detection algorithm are compared.The improved edge detection experiments show that the new algorithm is position detection accurate, continuity, and the advantages of less interference.
