  Adaptive Non-Local Means Denoising of MR Images with
  Spatially Varying Noise Levels

Developed by Jose V. Manjon and Pierrick Coupe
Modified by Dongjin Kwon

Usage:

naonlm3d -i [input_image_file] -o [output_image_file]

Options:
  -i (--input  ) [input_image_file]  : input image file (input)
  -o (--output ) [output_image_file] : output image file (output)
  -v (--search ) [integer]           : radius of the 3D search area (default=3, option)
  -f (--patch  ) [integer]           : radius of the 3D patch used to compute similarity (default=1, option)
  -r (--rician ) [1 or 0]            : 1 (default) if apply rician noise estimation, 0 otherwise (option)
