The proposed Matlab package DWIdenoisingPackage contains six denoising filters and a noise estimation method for 4D DWI.
The package includes nonlocal means, local PCA and Oracle DCT methods.
Based on image redundancy and/or sparsity, the proposed filters provide efficient denoising while preserving fine structures.
The package is compiled for Linux (64 bits), Windows (64 bits) and MAC (64bits). The proposed GUI enables the processing of several .nii files in 2-clicks to make easier the processing of large database.
