Joint Anisotropic LMMSE Filter for Stationary Rician noise removal in DWI
All these estimations are performed as sample estimates in a 'shaped neighborhood' defined by the weights extracted from the structural similarity of the voxels following the same idea as in the Non-Local Means filter.
This C++ code can be compiled as either a standalone (ITK required. Versions 3 and 4 are supported) or as a CLI module for 3-D Slicer (versions 3 and 4). Only "nhdr/nrrd" DWIs are supported.
