	int x,
	int y,
	int radius
)

Parameters

x
Type: SystemInt32
X coordinate of the point to calculate wavelet at.
y
Type: SystemInt32
Y coordinate of the point to calculate wavelet at.
radius
Type: SystemInt32
Wavelet size to calculate.

Return Value

Type: Int32
Returns value of the horizontal wavelet at the specified point.
Remarks

The method calculates horizontal wavelet, which is a difference of two horizontally adjacent boxes' sums, i.e. A-B. A is the sum of rectangle with coordinates (x, y-radius, x+radius-1, y+radius-1). B is the sum of rectangle with coordinates (x-radius, y-radius, x-1, y+radiys-1).
