Denoising Hyperspectral Images

The spectral total variation (STV) denoising algorithm is a new denoising algorithm for hyperspectral images that estimates different noise levels across the spectral axis from observed data. 

The code can also be downloaded from Matlab FileExchange : http://www.mathworks.com/matlabcentral/fileexchange/52478-the-spectral-total-variation-denoising-algorithm
