Constructor & Destructor Documentation

mrpt::vision::CGaussianConvolutionKernel::CGaussianConvolutionKernel	(	float	sigma,
		bool	isDOG
	)

The constructor is given the "sigma" value (in pixels) to precompute the gaussian and DOG lookup tables.

Parameters:

	sigma	The sigma value of the Gaussian.
	isDOG	Set to false to obtain a Gaussian kernel, or false to obtain a DOG filter.
