Class SplineFitter

java.lang.Object
ij.measure.SplineFitter
public class SplineFitter
extends Object
This class fits a spline function to a set of points. It is based on the InitSpline() and EvalSine() functions from XY (http://www.trilon.com/xv/), an interactive image manipulation program for the X Window System written by John Bradley. Eric Kischell (keesh@ieee.org) converted these functions to Java and integrated them into the PolygonRoi class.

    Constructor Description
    SplineFitter​(float[] x, float[] y, int n)  
    SplineFitter​(float[] x, float[] y, int n, boolean closed)
    For closed curves: the first and last y value should be identical; internally, a periodic continuation with a few will be used at both ends
    SplineFitter​(int[] x, int[] y, int n)
