We present two methods for lossy compression of normal vectors through quantization using "base" polyhedra. The first revisits subdivision-based quantization. The second...
A fast inter-prediction mode decision and motion search algorithm is proposed for the H.264 video coding standard. The multi-resolution motion estimation scheme and an adaptive ra...
Modern computer viruses spread incredibly quickly, far faster than human-mediated responses. This greatly increases the damage that they cause. This paper presents an approach to ...
Abstract. We introduce the concept of Dynamic Rate Shaping, a technique to adapt the rate ofcompressed video bitstreams MPEG-1, MPEG2, H.261, as well as JPEG to dynamically varyi...
This paper presents a set of fast algorithm and VLSI architecture for HDTV-sized H.264 fractional motion estimation. To solve the long computational latency in HD-sized applicatio...
