Fast detection for edges of circle and ellipse
Hou Yun Yu · Journal of China Institute of Metrology · 2000
Based on the Hough transform,a quick algorithm for the edge detection of circles and ellipses is presented by using a pair of points of pictures as well as their invariants under translation、scale and rotation in this paper.The shortages in Ref\\. are replenished.The experiment examples indicate that the algorithm is easy in use,high of calculation speed,insensitive for noise and can be flexibly used for some difficult edge detection problems.
