class | itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::AddMultConstFunctor |
class | itk::DeformationFieldJacobianDeterminantFilter< TInputImage, TRealType, TOutputImage > |
Computes a scalar image from a vector image (e.g., deformation field) input, where each output scalar at each pixel is the Jacobian determinant of the vector field at that location. This calculation is only correct if the the vector field has values that are the absolute locations from which to get the new values. This implies that the identity vector field (VF) mapping would have values at each location (x) equal to the location itself. VF(x)=x. THIS IS VERY UNUSUAL. The DeformationFieldJacobianDeterminantFilter computes the proper Jacobian Determinant for a vector field described this way as det[ dT/dx ] = det[ du/dx ]. More... | |
class | itk::DifferenceOfGaussiansGradientImageFilter< TInputImage, TDataType > |
Performs difference-of-gaussians gradient detection. More... | |
class | itk::DisplacementFieldJacobianDeterminantFilter< TInputImage, TRealType, TOutputImage > |
Computes a scalar image from a vector image (e.g., deformation field) input, where each output scalar at each pixel is the Jacobian determinant of the vector field at that location. This calculation is correct in the case where the vector image is a "displacement" from the current location. The computation for the jacobian determinant is: det[ dT/dx ] = det[ I + du/dx ].
