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,
                        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.
