public class AlgorithmBSmooth
extends AlgorithmBase

Smoothing of VOI using 1 iteration of bSplines. All selected curves in all slices of the voi will be smoothed. The number of interpolated points is user selectable. The user chooses whether or not to trim out nearly collinear points. The user chooses whether or not to remove the original selected curve. If the original curve is not removed, the new curve will have a different color. If the original curve is removed, the new curve will have the same color.
