Constructor Detail

FourierDescriptorFromPolygon

public FourierDescriptorFromPolygon(Point2D[] V,
                                    int Mp)

Parameters:

V - sequences of 2D points describing an arbitrary, closed polygon.

Mp - the number of Fourier coefficient pairs (M = 2 * Mp + 1).

FourierDescriptorFromPolygon

public FourierDescriptorFromPolygon(ij.gui.Roi roi,
                                    int Mp)

Parameters:

roi: - a region of interest (ImageJ), not necessarily a polyline.

Mp: - the number of Fourier coefficient pairs (M = 2 * Mp + 1)
