Detailed Description

Applies a symmetric Gaussian filter to an image.

Algorithm is based on separable convolution. Guarantees identical results between OpenGL and CPU modes, up to numerical precision (which is slightly higher on CPU).

Public Member Functions
	GaussianFilter (unsigned int kernelRadius=3, double sigma=1.0)

void	setSigmaInPixels (double sigma)
	Set standard deviation for Gauss curve in pixels, does not change kernel size.

void	setKernelRadius (unsigned int r)
	Set kernel radius, total size is 2*r+1 pixels. Does not change sigma.

bool	setSigmaAsCutoffRatio (double cutoffRatio)
	Sets sigma such that at the kernel edge the Gauss has cutoffRatio of its peak value. Returns whether value was valid.

void	setUseGPU (bool val)

void	setIgnoreOutside (bool val)
