Detailed Description

template<typename TInputImage, typename TRealType = float, typename TOutputImage = TInputImage>
class rtk::SingularValueThresholdImageFilter< TInputImage, TRealType, TOutputImage >

Performs thresholding on the singular values.

The image is assumed to be of dimension N+1, and to contain itk::CovariantVector of length N. The last dimension is assumed to be the channel dimension (color, or time, or materials in spectral CT), of size L. The input image must contain the spatial gradient of each channel.

The filter walks the pixels of a single channel. For each of these pixels, it constructs a matrix by concatenating the gradient vectors of the L channels. The matrix is decomposed using SVD, its singular values are thresholded, and then reconstructed. The resulting matrix is then cut back into L gradient vectors, which are written in output.
