... algorithm. The basic principle of the algorithm is to update the K-SVD dictionary iteratively by using fast iterative shrinkage threshold algorithm (FISTA) and K-singular value decomposition (K-SVD). The updated K-SVD dictionary is used for sparse representation of seismic data to remove the small value...
