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 | itk::MaskFeaturePointSelectionFilter< TImage, TMask, TFeatures > |
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 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.
