This voting procedure is carried out in a parameter space, from which object candidates are …
Web1.6 Accumulation into (a;b)-space using circular Hough transform The idea of the Hough transform is that perpendiculars to edge points of a circle cross in the centre of the circle. Therefore, if we draw perpendicular lines to every edge point of our edge map, we should obtain bright ‘hot spots’ in the centres of the circles.
