Non Negative K-SVD algorithm



The NN-K-SVD algorithm finds a non-negative dictionary for linear representation of signals. Given a set of signals, it searches for the best dictionary that can sparsely represent each signal.

Detailed discussion on the algorithm and possible applications can be found in “K-SVD and its non-negative  variant for dictionary design”, written by M. Aharon, M. Elad, and A.M. Bruckstein  and appeared in the Proceedings of the SPIE conference wavelets, Vol. 5914, July 2005.
