Image compression using learned dictionaries by RLS-DLA and compared with K-SVD
The recently presented recursive least squares dictionary learning algorithm (RLS-DLA) is tested in a general image compression application. Dictionaries are learned in the pixel ...

Integrated Sidelobe Level of sets of Rotated Legendre Sequences
We here address the problem of constructing sets of sequences with low integrated aperiodic auto- and crosscorrelations when the constraint of antipodal symbols is enforced. Our m...

Adaptation of source-specific dictionaries in Non-Negative Matrix Factorization for source separation
This paper concerns the adaptation of spectrum dictionaries in audio source separation with supervised learning. Supposing that samples of the audio sources to separate are availa...

Localized filtering for artifact removal in compressed images
The paper proposes a novel method for coding artifact reduction in compressed images. For removing blocking artifacts, a localized DCT-based filter with condition on the similari...
