Method Summary

float	getIntegralSquare(int xA, int yA, int xD, int yD) The method needs only A and D, i.e. the upper left and bottom right vertex coordinates.
float	getIntegralValue(int x, int y) Given the coordinates of a point of the image, returns its integral value, ie the intensity of the rectangle whose vertices are the origin and (x, y).

Method Detail

getIntegralValue

float getIntegralValue(int x,
                       int y)

Given the coordinates of a point of the image, returns its integral value, ie the intensity of the rectangle whose vertices are the origin and (x, y).

Parameters:

x - x-coordinate

y - y-coordinate

Returns:

The integral value of the given point.

getIntegralSquare

float getIntegralSquare(int xA,
                        int yA,
                        int xD,
                        int yD)

The method needs only A and D, i.e. the upper left and bottom right vertex coordinates.

Parameters:

xA - x-coordinate of vertex A.

yA - y-coordinate of vertex A.

xD - x-coordinate of vertex D.

yD - y-coordinate of vertex D.

Returns:

The integral value of the square.
