Class IntensityEnergy

java.lang.Object
  snakeprogram.IntensityEnergy

All Implemented Interfaces:

ImageEnergy

public class IntensityEnergy
extends java.lang.Object
implements ImageEnergy

Calculates an energy based on the intensity of the image. The snake points are pushed towards the brightest regions.

Constructor Summary

IntensityEnergy(ij.process.ImageProcessor img, double blur_sigma)

Method Summary

double[]	getImageEnergy(double x, double y) Given the coordinate points this will calculate the image energy and return the value as a double[] Ex Ey
double	getMaxPixel(double x, double y) This will use the squaresize defined in TwoDDeformation, and the original image to find the maximum pixel value in the square.
ij.process.ImageProcessor	getProcessor() returns the original imageprocessor, that has been converted to a float

getImageEnergy

public double[] getImageEnergy(double x,
                               double y)

Description copied from interface: ImageEnergy

Given the coordinate points this will calculate the image energy and return the value as a double[] Ex Ey

getMaxPixel

public double getMaxPixel(double x,
                          double y)

Description copied from interface: ImageEnergy

This will use the squaresize defined in TwoDDeformation, and the original image to find the maximum pixel value in the square. This is used for determining the head force on the filament.

getMaxPixel in interface ImageEnergy

getProcessor

public ij.process.ImageProcessor getProcessor()

Description copied from interface: ImageEnergy

returns the original imageprocessor, that has been converted to a float
