Abstract Many Edge detection methods are developed so far .Ant Colony Optimization is an algorithm inspired by the nature to solve the computational problems.ACO uses the concept of collective activities of ants, that they are self-organized and work without a central control. In this thesis modification in the ACO algorithm is proposed. First step in ACO algorithm is the initialization of ants. Then ants are moved from one node to another followed by updating the pheromone matrix. In this thesis the ant’s position are logically initialized using the intensity variation in the grayscale image. Each ant’s movement is influenced by the heuristic information. Further the algorithm was followed by the condition for updating the ant’s pheromone concentration and stopping the ant movement. Finally the binary decision was made whether the detected edge is correct or not using threshold method. The detected edge map is compared with traditional edge detectors and also with the ACO algorithm. Comparison is done using parameters Figure of Merit, Hausdorff Distance and BDM. The experiment was performed on software MATLABR2008 using images of size 128 128.
