Classes

class  itk::BilateralImageFilter< TInputImage, TOutputImage >
 Blurs an image while preserving edges. More...
class  itk::DanielssonDistanceMapImageFilter< TInputImage, TOutputImage, TVoronoiImage >
 This filter computes the distance map of the input image as an approximation with pixel accuracy to the Euclidean distance. More...
class  itk::DerivativeImageFilter< TInputImage, TOutputImage >
 Computes the directional derivative of an image. The directional derivative at each pixel location is computed by convolution with a derivative operator of user-specified order. More...
class  itk::DiscreteGaussianDerivativeImageFilter< TInputImage, TOutputImage >
 Calculates image derivatives using discrete derivative gaussian kernels. This filter calculates Gaussian derivative by separable convolution of an image and a discrete Gaussian derivative operator (kernel). More...
class  itk::DiscreteGaussianImageFilter< TInputImage, TOutputImage >
 Blurs an image by separable convolution with discrete gaussian kernels. This filter performs Gaussian blurring by separable convolution of an image and a discrete Gaussian operator (kernel). More...
class  itk::FastChamferDistanceImageFilter< TInputImage, TOutputImage >
 This class compute the signed (positive and negative) chamfer distance in a narrow band. More...
class  itk::HoughTransform2DCirclesImageFilter< TInputPixelType, TOutputPixelType >
 Performs the Hough Transform to find circles in a 2D image. More...
class  itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >
 Performs the Hough Transform to find 2D straight lines in a 2D image. More...
class  itk::ImagePCAShapeModelEstimator< TInputImage, TOutputImage >
 Base class for ImagePCAShapeModelEstimator object. More...
class  itk::ImageShapeModelEstimatorBase< TInputImage, TOutputImage >
 Base class for statistical shape model estimation. More...
class  itk::LaplacianImageFilter< TInputImage, TOutputImage >
class  itk::LaplacianSharpeningImageFilter< TInputImage, TOutputImage >
 This filter sharpens an image using a Laplacian. LaplacianSharpening highlights regions of rapid intensity change and therefore highlights or enhances the edges. The result is an image that appears more in focus. More...
class  MaskFeaturePointSelectionFilter
 Generate a PointSet containing the feature points selected from a masked 3D input image. More...
class  itk::SignedDanielssonDistanceMapImageFilter< TInputImage, TOutputImage, TVoronoiImage >
class  itk::SignedMaurerDistanceMapImageFilter< TInputImage, TOutputImage >
 This filter calculates the Euclidean distance transform of a binary image in linear time for arbitrary dimensions. More...
class  itk::SobelEdgeDetectionImageFilter< TInputImage, TOutputImage >
 A 2D or 3D edge detection using the Sobel operator. More...
class  itk::ZeroCrossingBasedEdgeDetectionImageFilter< TInputImage, TOutputImage >
 This filter implements a zero-crossing based edge detecor. More...
class  itk::ZeroCrossingImageFilter< TInputImage, TOutputImage >
 This filter finds the closest pixel to the zero-crossings (sign changes) in a signed itk::Image. More...

 Image Gradient Filters

Detailed Description

Image feature extraction filters process an image to extract features of interest such as gradients, edges, distances, etc. Examples of image feature extraction algorithms available in ITK are: image gradients, first and second derivatives, and Danielson distance.
