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.
 

Method Detail

makeConvolutionDx

float makeConvolutionDx(int x,
                        int y,

                        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.

Parameters:
x -
y -
_scale - Detected Interest Point scale.
Returns:
float Haar Convolution value in the y-direction for the specified Interest Point.
