In recent years the MPEG-4 ISO compression standard has gained much attention. With its high compression ratio it promises to make broadbandstreaming more feasible. However, curre...
This paper describes a series of algorithms that allow the unconstrained walkthrough of static scenes shaded with the results of precomputed global illumination. The global illumin...

We present a fully automatic system for 2D model-based image coding of human faces for potential applications such as video telephony, database image compression, and face recogni...
Variable-Length Encoding (VLE) is a process of reducing input data size by replacing fixed-length data words with codewords of shorter length. As VLE is one of the main building bl...
