Detailed Description

Deconvolve an image using the Landweber deconvolution algorithm.

This filter implements the Landweber deconvolution algorthm 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 .
