This code contain two algorithms for reducing random valued impulse noise as well as salt and pepper noise.
One is synthesis prior formulation and other is total variation based formulation. Both the algorithms are based on split Bregman approach.
Both the algorithms are described in our research paper titled "Generalized Synthesis and Analysis Prior Algorithms with Application to Impulse Denoising". PDF of this paper is available from my homepage " http://www.iiitd.edu.in/~hemanta/ ".
Run demoXXX.m files to see how the algorithms are working.
