Detailed Description

Gaussian filter class.

Constructor & Destructor Documentation

vpGaussianFilter()

vpGaussianFilter::vpGaussianFilter	(	unsigned int	width,
		unsigned int	height,
		float	sigma,
		bool	deinterleave = false
	)

Gaussian filter constructor.

Parameters

[in]	width	: image width.
[in]	height	: image height.
[in]	sigma	: Standard deviation for Gaussian kernel.
[in]	deinterleave	: if true, deinterleave R, G, B channels and perform Gaussian filter on each individual channel. It can be faster to deinterleave when repeatedly calling Gaussian filter with the same sigma and the same image resolution.
