Description

The NLmCED (Non Local mean Coherence Enhancing Diffusion) filter is a denoising tool aimed to reduce Rician Noise in 3D MR images. It is a combination between two filters such as the Non-Local mean filter and the Anisotropic Diffusion tensor method with an estimator of Rician noise. The NLmCED filter can benefit from the noise reduction capabilities of the NLM filter while maintaining the edge-preserving characteristics of anisotropic diffusion.

Usage

jobman submit -i nlmced -- <input_dir> <output_dir> [iter] [rho] [alpha] [wind]

NLmCED filter is an iterative filter with some parameters to be set:

  • input_dir: the input path of a dataset directory.
  • output_dir: the output directory where the results will be saved.
  • iter (optional): iteration number (default value: 1).
  • rho (optional): (ρ) a standard deviation of the Gaussian kernel for the creation of the structure tensor (default value: 0.01).
  • alpha (optional): (α) a single value to control the diffusion tensor matrix (default value: 0.01).

Example:

  jobman submit -i nlmced -- ~/datasets/87f3be56-4725-45c3-9baa-d338de530f73/ ~/persistent-home/nlmced-results/ 1 0.01 0.01

Note the output directory path should be any within the persistent-home, which is shared between all desktops and jobs created by the user,
otherwise the results will be lost after the end of the job.
