Dual-tree complex wavelet combined with non-local means for ASL fMRI denoising

Dual-tree complex wavelet combined with non-local means ASL fMRI denoising is a software toolbox that can denoise MR images, especially ASL fMRI images. The software:

(1) Reads and writes images in analyze format;
(2) Pre-processes ASL fMRI images and provides denoised images for further analysis;
(3) Achieves variable denoising outcomes by changing certain parameters;
(4) Can be employed for denoising other MR images, such as diffusion MRI,etc.

The method is described in the following paper:
Voxel-wise functional connectomics using arterial spin labeling fMRI: the role of denoising.
