Image Gradient Filters
[Image Feature Extraction Filters]

Classes
class	DeformationFieldJacobianDeterminantFilter
	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. More...
class	DifferenceOfGaussiansGradientImageFilter
	Performs difference-of-gaussians gradient detection. More...
class	GradientImageFilter
	Computes the gradient of an image using directional derivatives. More...
class	GradientMagnitudeImageFilter
	Computes the gradient magnitude of an image region at each pixel. More...
class	GradientMagnitudeRecursiveGaussianImageFilter
	Computes the Magnitude of the Gradient of an image by convolution with the first derivative of a Gaussian. More...
class	GradientRecursiveGaussianImageFilter
	Computes the gradient of an image by convolution with the first derivative of a Gaussian. More...
class	HessianRecursiveGaussianImageFilter
	Computes the Hessian matrix of an image by convolution with the Second and Cross derivatives of a Gaussian. More...
class	LaplacianRecursiveGaussianImageFilter
	Computes the Laplacian of an image by convolution with the second derivative of a Gaussian. More...
class	VectorGradientMagnitudeImageFilter
	Computes a scalar, gradient magnitude image from a multiple channel (pixels are vectors) input. More...
