The memory system's large and growing contribution to system performance motivates more aggressive approaches to improving its efficiency. We propose and analyze a memory hie...
This paper proposes a new image compression scheme by introducing visual patterns to nonlinear interpolative vector quantization (IVQ). Input images are first distorted by a gener...
3D models have become an essential element of multimedia applications because they provide visual effects that permit interactive exploration. As in other media types, efficient c...
