Detailed Description

template<typename TInputImage, typename TKernelImage = TInputImage, typename TOutputImage = TInputImage, typename TInternalPrecision = double>
class itk::LandweberDeconvolutionImageFilter< TInputImage, TKernelImage, TOutputImage, TInternalPrecision >

Deconvolve an image using the Landweber deconvolution algorithm.

This filter implements the Landweber deconvolution algorithm as defined in Bertero M and Boccacci P, "Introduction to Inverse Problems in Imaging", 1998. The algorithm assumes that the input image has been formed by a linear shift-invariant system with a known kernel.

The Landweber algorithm converges to a solution that minimizes the sum of squared errors \(||f \otimes h - g||\) where \(f\) is the estimate of the unblurred image, \(\otimes\) is the convolution operator, \(h\) is the blurring kernel, and \(g\) is the blurred input image. As such, it is best suited for images that have zero-mean Gaussian white noise.

This is the base implementation of the Landweber algorithm. It may produce results with negative values. For a version of this algorithm that enforces a positivity constraint on each intermediate solution, see ProjectedLandweberDeconvolutionImageFilter.

This code was adapted from the Insight Journal contribution:
