Method Summary

void	copy(Hist srcHist) make a copy of an source histogram in the current histogram
void	createFromImage(int imgWidth, int imgHeight, int[] pixels) fill the current (color) histogram with the source image pixels, i.e crate an histogram of the source image
int	getBinsPerComp() return the the number of bit per component (usually choosed by the user trought the implementation class's constructor)
int	getBinValue(int bin) return the content of the queried bin
void	normalize(float[] destination, int norm) normalize with "norm" factor, the current histogram, put the result histogram in "destination" array
void	sumHists(Hist leftHist, Hist upHist, Hist up_leftHist, int currentPixel) sum the surce histograms using the algorithm proposed by Fatih Porikli (http://www.merl.com) (you can check the algorithm in it's pure form in our "Histogram" implementation class)
void	sumPixel(int pixelColor) update the current histogram with the source pixel value
