Image Gradient Filters

Collaboration diagram for Image Gradient Filters:

Classes
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 ]. More...
class	itk::GradientImageFilter< TInputImage, TOperatorValueType, TOutputValueType, TOutputImageType >
	Computes the gradient of an image using directional derivatives. More...
class	itk::GradientMagnitudeImageFilter< TInputImage, TOutputImage >
	Computes the gradient magnitude of an image region at each pixel. More...
class	itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >
	Computes the Magnitude of the Gradient of an image by convolution with the first derivative of a Gaussian. More...
class	itk::GradientRecursiveGaussianImageFilter< TInputImage, TOutputImage >
	Computes the gradient of an image by convolution with the first derivative of a Gaussian. More...
class	itk::HessianRecursiveGaussianImageFilter< TInputImage, TOutputImage >
	Computes the Hessian matrix of an image by convolution with the Second and Cross derivatives of a Gaussian. More...
class	itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >
	Computes the Laplacian of Gaussian (LoG) of an image. More...
class	itk::VectorGradientMagnitudeImageFilter< TInputImage, TRealType, TOutputImage >
