public class Circle_Fitting extends Object implements PlugInFilter, JavaDocHelp

ImageJ plugin, performs algebraic circle fitting on the current ROI to find an initial circle, followed by geometric fitting. Algebraic and geometric fitting methods can be selected (see Sec. 11.1 of [1] for details). If successful, the resulting ellipses are displayed as a vector overlay (color can be chosen). Sample points are either collected from the ROI (if available) or collected as foreground pixels (values > 0) from the image. If no image is currently open, the user is asked to create a suitable sample image.
