Discrete transform techniques form the mathematical foundation of modern image and video compression by converting spatial or temporal pixel data into spectral coefficients that reveal salient ...

Compression is one of the most important criteria in determining quality and cost of ownership in a digital video system. Advances in processing power enable more sophisticated compression techniques.

If bandwidth and storage were infinite and free, there would be no need for video compression. However, bandwidth is always limited; the per-byte price of storage decreases over time but it's never ...

Hype has quickly been building around wireless video for the past few years. With 2.5G and 3G systems on the way, many have started to view the delivery of video content to mobile phones as one of the ...
