Abstract
A method and apparatus is provided for producing a smooth closed curve from a binary mask such as the type produced when segmenting various parts of a human body. Points defining the segmentation boundary are transformed into a set of polar coordinates. The set of coordinates is thresholded and averaged, and then smoothed using a window smoothing technique. The resulting boundary points are curve fit to produce the smooth closed curve.
