this paper/code gives a very good method on image denoising. i think this method is complex and high performance. first, shape-adaptive DCT, then soft/hard threshold denosing, lastly, wiener denoising.
To improve the performance of the two-way denoise-and-forward network coding opportunistic relaying systems (TW-DNF-OR), two novel best-relay selection criterions are presented, which are the jointing adaptive modulation max-min criterion (AM-MM) and
