摘要: MPEG-4 is the multimedia standard for combining interactivity, natural and synthetic digital video, audio computer-graphics. Typical applications are: internet, video conferencing, mobile videophones, cooperative work, teleteaching games. With next step from block-based (ISO/IEC MPEG-1, MPEG-2, CCITT H.261, ITU-T H.263) to arbitrarily-shaped visual objects taken. This significant demands a new methodology system analysis design meet considerably higher flexibility of MPEG-4. Motion estimation central part MPEG-1/2/4 H.261/H.263 compression standards has attracted much attention in research industry, following reasons: it computationally most demanding algorithm encoder (about 60-80% total computation time), high impact on quality encoder, not standardized, thus being open competition. Algorithms, Complexity Analysis, VLSI Architectures Estimation covers detail every single or compliant encoder: Fast motion algorithms tools Detailed complexity software implementation fast within Design space architectures examples (1) throughput (2) low-power estimator. Analysis an important introduction numerous algorithmic, architectural aspects As such, all researchers, students practitioners working image processing, coding will find this book interest.
