The Image Edge Extraction Algorithm Based on Hough Transform Coupling Ant Colony Optimization
In order to solve the image edge detection algorithm
the edge information is affected by the noise
causing the image edge positioning accuracy is low
Edge information loss and false edges and other issues
proposed a image edge extraction algorithm based on Hough transform (HT)coupling ant colony optimization(ACO).Firstly
introducing the Hough transform to the input image
eliminating the effect of noise and line segment. Secondly
the difference between the pixel gradient of the image and the statistical average of the circular neighborhood is calculated
and the weight function between the two is constructed
and the pheromone and the heuristic information are used as the ant colony. Finally
the ant colony optimization algorithm is used to guide the ant colony to search the edge of the image
so as to finish the image edge extraction. The simulation results show that compared with the current edge detection algorithm
the edge location accuracy and the edge details are abundant
which can effectively restrain the noise
and has better robustness.
