Novel 2-D Hough planes for the detection of ellipses

A new approach of the Hough transform for the detection of ellipses is presented in this paper. In our algorithm, the search of a 5-D Hough domain is replaced with four 2-D Hough planes. One of the main differences between our proposed transform and other techniques is the approach to extract feature points in an image for the recognition. For the accumulation process in the Hough domain, an inherent property of our suggested algorithm is its capability to effect verification. Hence, significant improvement on the performance of the recognition is achieved. Furthermore, our proposed algorithm is applicable for the detection of both circular and elliptical objects concurrently
