Member Function Documentation

template<class TFloat = double>

static std::vector<TFloat> cmtk::GaussianKernel< TFloat >::GetHalfKernel	(	const Units::GaussianSigma &	sigma,
		const TFloat	maxError = 1e-5
	)		[inline, static]

Create half kernel, starting with center element.

Parameters:

sigma	Sigma parameter (standard deviation) of the kernel
maxError	Maximum approximation error: the kernel radius is computed so that truncated elements are below this value
