Constructor Summary

My_HAAR_Convolution(Integral_Image integralImage)

Method Summary

float	makeConvolutionDx(int x, int y, float _scale) Computes the response in x-direction and returns the value of the (x,y) point for a filter proportional to the interest point detected scale.
float	makeConvolutionDy(int x, int y, float _scale) Computes the response in y-direction and returns the value of the (x,y) point for a filter proportional to the interest point detected scale.
