A-Functions: A generalization of Extended Baum-Welch transformations to convex optimization
We introduce the Line Search A-Function (LSAF) technique that generalizes the Extended-Baum Welch technique in order to provide an effective optimization technique for a broader s...

Rate-distortion Optimization For Automatic Sprite Video Coding Using H.264/avc
Sprite-based video coding offers higher compression efficiency than conventional block-based hybrid video coders. In sprite coding a sequence is divided into a model of its backgr...

Coding structure optimization for interactive multiview streaming in virtual world observation
—While most multiview coding techniques focus on compressing all frames in a multiview video sequence in a ratedistortion optimal manner, in this paper we address the problem of ...

Run-Time Optimization of Sparse Matrix-Vector Multiplication on SIMD Machines
Sparse matrix-vector multiplication forms the heart of iterative linear solvers used widely in scientific computations (e.g., finite element methods). In such solvers, the matrix-v...
