Detailed Description

template<class T, unsigned int VDimension>
class itk::PSMImageDomainWithCurvature< T, VDimension >

An image domain that extends PSMImageDomainWithHessianGradients with Hessian information. Hessian values are interpolated with the SampleCurvature(point) method. Curvature may be smoothed by specifying a sigma for Gaussian blurring of the image prior to initialization.
