Some methods from different authors to estimate the level of noise out of a MR image. Methods assume an underlying Rician or noncentral chi model.

Most Methods do not require a previous segmentation of the background.

All methods proposed by several author until 2009, and reviewed in

Santiago Aja-Fernández, Antonio Tristán-Vega, Carlos Alberola-López, Noise estimation in single- and multiple-coil magnetic resonance data based on statistical models, Magnetic Resonance Imaging, Volume 27, Issue 10, Pages 1397-1409

Toolbox includes folder with LocalStat toolbox (local statistics processing toolbox). It includes "localmean", "localvar" and mode calculation.

Not getting correct values for for multiple coil images. Do we need to change the parameters.

Anyone knows what the input parameter represent? Many thanks.
