Fast and Accurate Circle Detection Algorithm for Porous Components
In this paper, a fast and accurate circle detection algorithm is presented. The proposed algorithm satisfies the application requirements on accurate circle localization for porous components with excellent real-time performance. The core idea of the algorithm is to cluster circle edge points by an easy-to-implement image analysis technique. Specifically, the original image is firstly down sampled with uniformly spaced grid to form an image with smaller size. The new image is then analyzed, pixel by pixel, to find the candidate grid points located inside the circle on the original image. Secondly, candidate... view more»
