Abstract 

Digital image processing and in particular video processing are highly data
intensive i.e. memory and bandwidth consuming computer applications. Thus
image and video compression get more and more important. Besides the
conventional DCT transform coding methods, wavelet transforms have been
established, having better still image rate distortion performance while
being fast enough for real-time video implementation. This talk gives a
survey on methods and implementations of high performance compression
algorithms and contemporary and future standards (JPEG 2000, H26L,...) and
their applications like multipoint videoconferencing over IP.


Hans L. Cycon received his diploma in physics in 1975 and his Phd in
mathematics in 1979 (habilitation 1984) from the Technical University
Berlin, Germany. From 1985 trough 1990 he was with Siemens cooperation
working on software development and software engineering for digital
telecommunication systems. He was teaching mathematics and physics at the
Telekom Fachhochschule Germany and is since 1995 Professor at FHTW teaching
mathematics and signal processing. His publications fields (including a
book) are mathematical physics and signal processing i.e. image coding.
He is member of the german delegation of the ITU/ISO standardization
committee for JPEG 2000 still image standard.
