NormalKernel2D Method

public static double[,] Kernel2D(
	double sigmaSquared,
	int size
)

Public Shared Function Kernel2D ( 
	sigmaSquared As Double,
	size As Integer
) As Double(,)

Parameters

sigmaSquared

Type: SystemDouble
The variance parameter σ² (sigma squared).

size

Type: SystemInt32
Kernel size (should be odd), [3, 101].

Return Value

The function calculates 2-D Gaussian kernel, which is array of Gaussian function's values in the [-r, r] range of x,y values, where r=floor(size/2).
