Compression standards and alternative methods for video telecom

The complex video compression methods in the process of being standardized, which are designed to reduce transmission needs by detecting and coding image redundancy temporally and spatially between frames, are examined. Methods involving fractals, and wavelets may achieve more efficient coding by defining spatial formats and equations more applicable to the specific image than the more general-purpose transforms of the standards. A newer method involves the capture of an entire database of image characteristics and identifies and stores the 3-D motion in the image field. The image can be reproduced at high compression rates at remote locations. Telecommunication products that facilitate the operation and use of video compression systems are presented.<>
