Gradient-Based Methods for Sparse Recovery
The convergence rate is analyzed for the sparse reconstruction by separable approximation (SpaRSA) algorithm for minimizing a sum f(x) + ψ(x), where f is smooth and ψ is convex, ...

Frequency Weighting and Selective Enhancement for MPEG-4 Scalable Video Coding
In MPEG-4 scalable video coding, only a small portion of input data is coded in the base layer, and most signal components remain in enhancement layers. In this paper, we propose a...
