WebbThe circle Hough Transform (CHT) is a basic feature extraction technique used in digital image processing for detecting circles in imperfect images. The circle candidates are produced by “voting” in the Hough parameter space and then selecting local maxima in an accumulator matrix. It is a specialization of the Hough transform . WebbCircle detection using randomized sampling has been developed in recent years to reduce computational intensity. However, randomized sampling is sensitive to noise that can lead to reduced accuracy and false-positive candidates. WebbThe randomized circle detection algorithm is chosen based on the fact that for a circle, the gradient vector of the edge pixels will always point to the center of the circle. purely informative
