Fig. 5From: Line and circle detection using dense one-to-one Hough transforms on greyscale imagesInfluence of the multiscale voting on the two-pass one-to-one DHT for circle detection. The image represents 15 black disks with radii ranging between 3 and 30 on a white background, with a Gaussian noise of 20%. Left: the original image with the 15 best circles overlaid in red. Right: the output of the first pass of the two-pass DHT (centre localisation)Back to article page
