Abstract

Three new methods for fitting ellipses to regions are presented. They are based on the measurements of the support function of the region. The fitted ellipse is the one that: (1) minimizes the support function error, (2) circumscribes the region or (3) is inscribed in the region. These methods have the advantage of fitting an ellipse to a region without the need of the contour. They can be used on incomplete ellipses. Results are presented on simulated data and a real nuclear medicine image of the myocardium
