WIENERC modifies the WIENER2 function from the MATLAB image toolbox to provide proper noise estimation (assuming additive Gaussian noise)

Four noise methods implemented:

-Mode of local variance (recommended)
-Median of local variance
-Minimum of local variance
-Median absolute deviation based.

Methods proposed in:

S. Aja-Fernández, G. vegas-Sanchez-Ferrero, M. Martín-Fernández and C. Alberola-López, "Automatic Noise Estimation in Images Using Local Statistics. Additive and Multiplicative Cases". Image and Vision Computing, Vol. 27, Issue 6, May 2009, pp. 756-770.
