A lossy compression method used for color images and video. Instead of compressing small blocks of 8x8 pixels (64 bits) as in JPEG and MPEG, the wavelet algorithms compress the entire image with ...

Led by CalTech computer science professor Peter Schröder and Wim Sweldens of Bell Labs' Mathematical Sciences Research Center, scientists have developed an algorithm ...

A standard for compressing still images from the Joint Photographic Experts Group. Introduced in 2000, JPEG 2000 uses wavelet compression and provides greater compression ratios than the discrete ...

A strong contender is wavelet theory, a mathematical framework that powers image and video compression across the digital universe. Belgian physicist Ingrid Daubechies and French mathematicians ...

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.
