nlmeans

Arguments:

• [guide],_patch_radius>0,_spatial_bandwidth>0,_tonal_bandwidth>0,_patch_measure_command    or
• _patch_radius>0,_spatial_bandwidth>0,_tonal_bandwidth>0,_patch_measure_command

Description:

Apply non local means denoising of Buades et al, 2005. on selected images.

The patch is a gaussian function of std_patch_radius.
The spatial kernel is a rectangle of radius spatial_bandwidth.
The tonal kernel is exponential (exp(-d^2/_tonal_bandwidth^2))
with d the euclidean distance between image patches.

Default values:

patch_radius=4, spatial_bandwidth=4, tonal_bandwidth=10 and patch_measure_command=-norm.
