Class TwoDContourDeformation

java.lang.Object
  snakeprogram.TwoDDeformation
      snakeprogram.TwoDContourDeformation

public class TwoDContourDeformation
extends TwoDDeformation

This type of curve is attached at the two end points and forms a closed loop

Constructor Summary

TwoDContourDeformation(java.util.ArrayList<double[]> vertex_X, ImageEnergy ie)

Method Summary

void	addSnakePoints(double msl) Interpolates the points that are too far apart, and removes points that are too close together.
void	energyWithGradient(double[] Vx, double[] Vy) Calculates only the image energy the closed contour does not have any other terms
void	initializeMatrix() This method intializes an array which will become the A matrix using the values of alpha, beta and gamma as well as the number of points in verticesX and verticesY
