Discusses recent advances in representation and communication of visual signals, focusing on key technologies including compression algorithms and standards, video conferencing and communication applications, and image processing methodologies and implementations. New techniques examined here are having a profound impact on multimedia computers, videophones, video-over-Internet, HDTV, digital satellite TV, and interactive computer games. Specific subjects include video compression using residual vector quantization, three-dimensional model-based image communication, and principles of halftoning with stochastic screens. Annotation c.
