On the Detection of Generic Conic Form Parameters Using Hough Transform

Hough Transform (HT) is a method for shape extraction from images based on accumulator array of the most voted form. This paper introduces a unique methodology to detect any conic equation parameters using HT idea. Based on the analysis of generic conic equation it is observed that is possible to unify its identification on images if some aspects are considered. The bases of the formulation here presented are the use of polar coordinates on the match of open or closed form and the parameters search sequence. In this way we can identify complex forms through of the union of several conic detections.
