WebA circle is represented mathematically as where is the center of the circle, and is the radius of the circle. From equation, we can see we have 3 parameters, so we need a 3D accumulator for hough transform, which would be highly ineffective. So OpenCV uses more trickier method, Hough Gradient Method which uses the gradient information of edges.

WebIn order to detect the circles, or any other geometric shape, we first need to detect the edges of the objects present in the image. The edges in an image are the points for which there is a sharp change of color. For instance, the edge of a red ball on a white background is a circle. In order to identify the edges of an image, a common ...
