Double sparsity: learning sparse dictionaries for sparse signal approximation
Abstract--An efficient and flexible dictionary structure is proposed for sparse and redundant signal representation. The proposed sparse dictionary is based on a sparsity model of ...

Interactive Streaming of Stored Multiview Video Using Redundant Frame Structures
—While much of multiview video coding focuses on the rate-distortion performance of compressing all frames of all views for storage or non-interactive video delivery over network...

Optimizing Memory Accesses For Spatial Computation
In this paper we present the internal representation and optimizations used by the CASH compiler for improving the memory parallelism of pointer-based programs. CASH uses an SSA-b...
