GaussianKernel1D

public GaussianKernel1D(double sigma)

Method Details

makeGaussKernel1D

public static float[] makeGaussKernel1D(double sigma)

Creates and returns a 1D Gaussian filter kernel large enough to avoid truncation effects. The length of the resulting array is odd. The returned kernel is normalized.

Parameters:

sigma - the width (standard deviation) of the Gaussian

Returns:

the Gaussian filter kernel

makeGaussKernel1D

public static float[] makeGaussKernel1D(double sigma,
 boolean normalize)

Creates and returns a 1D Gaussian filter kernel large enough to avoid truncation effects. The length of the resulting array is odd. The returned kernel is optionally normalized.

Parameters:

sigma - the width (standard deviation) of the Gaussian

normalize - set true to normalize the kernel

Returns:

the Gaussian filter kernel
