Webb3 apr. 2014 · RCD determines that circle is a possible circle based on distance criteria. After finding its center and radius, it checks the number of pixels lying on the boundary of this possible circle. This checking criterion is performed by calculating the distance between all edge pixels in the image and the boundary of this possible circle. WebbKey Words: circle detection; Hough transform; randomized algorithm. I. INTRODUCTION Detecting circles from a digital image is very important in shape recognition [5]. Hough transform (HT) [11, 16] is the most well-known method for circle detection.
