Fast extraction of ellipses
Runsheng Wang, Allen R. Hanson, Edward M. Riseman · 2003
The process for fast extraction is divided into two steps: first, it looks for the areas where there might be ellipses by using heuristic function and a pyramid structure; then it finds the parameters of the ellipses in each area searched by a method that combines transformation of the feature space, projection, and optimum approximation approaches. Experiments indicate that both fast processing speed and suitable ellipse parameters are obtained.>
