Application of Least Square Algorithm for Ellipses Detection
It is a significant process to automatically extract ellipses or elliptic image features in highly precise vision detection,especially to achieve rapid as well as accurate detection in complex environment.Fortunately,this paper provides an approach to solve the problem.We firstly detect the edge of images by using sub-pixel edge detection algorithm,and then determine the elliptical shapes,and eliminate the non-ellipses.For the complicated context and taking into account the occlusion of ellipses,we integrate the robust Hough transforms and slip window into randomized algorithm based on least square approach with the purpose of having got the veracious ellipse parameters,which proves that the approach is available for images in stability and accuracy.
