The implementation of a codec for real time applications such as video-conferencing at low bit rates is discussed. The discrete cosine transform has been used for compression, both...
We investigate methods of using CRC32 for compressing Web URL strings and sharing of URL lists between servers, caches, and URL switches. Using trace-based evaluation, we compare ...
This paper presents a power evaluation framework designed for estimating power consumption of a new video telephone compression standard, ITU-H.263, at the system level. A hierarc...
Mobile devices are increasingly relied on but are used in contexts that put them at risk of physical damage, loss or theft. We consider a fault-tolerance approach that exploits sp...
This paper investigates the task of identifying frequently-used pathways from video sequences of natural outdoor scenes. Path models are adaptively learnt from the accumulation of...
