The objective of this paper is to investigate a number of circle detection methods which are based on variations of the Hough Transform. The methods considered include the standard Hough Transform, the Fast Hough Transform of Li et al, two space saving approaches which are bused on those devised by Gerig and Klein and a two-stage method. We experimentally(More)
We consider the problem of detecting elliptical curves using Hough Transform methods. Storage and efficiency problems are overcome by decomposing the problem into two stages. The first stage uses a novel constraint as the basis for a Hough Transform to detect the ellipse center while the second stage finds the remaining parameters using a simple but(More)
