${\ell }_1$-K-SVD: A Robust Dictionary Learning Algorithm With Simultaneous Update

Subhadip Mukherjee, Rupam Basu, Chandra Sekhar Seelamantula

We develop a dictionary learning algorithm by minimizing the ${\ell }_1$ distortion metric on the data term, which is known to be robust for non-Gaussian noise contamination. The prop…
