Image and Video Compression
Avideh Zakhor, UC Berkeley
Scope and Audience
This course will focus on image and video compression techniques as
used in transmission and storage applications. The three fundamental
questions of (a) what to code (b) how to quantize, and (c) how to do
bit allocation will be discussed. The course can be useful to
researchers, practicing engineers, managers and technologists.
Elementary knowledge of signals and systems at the undergraduate level
will be assumed.
Outline
- Waveform coding: PCM, DPCM
- Transform coding: DCT, KLT
- Multi-resolutoin coding: subband, pyramid, wavelets;
- Scalar and vector quantization.
- Huffman, arithmetic, and run-length coding.
- Lossy vs. lossless coding: Liv-Zempel coding.
- Inter-frame coding for video: motion estimation and compensation
algorithms
- Pre and post processing techniques
- Color
- Image and video compression standards: JPEG and MPEG 1 and 2.
- Low bit rate video coding: MPEG4, model based coding;
- Scalable video compression;
- Transmission of video over ATM and IP.
- Video compression with robustness to noisy, wireless channels.
- Video storage strategies on parallel disk arrays for video servers.
Lecturer
Avideh Zakhor received the B.S. degree from California Institute of
Technology, Pasadena, and the S.M. and Ph.D. degrees from
Massachusetts Institute of Technology, Cambridge, all in electrical
engineering, in 1983, 1985, and 1987 respectively. In 1988, she
joined the Faculty at U.C. Berkeley where she is currently
Associate Professor in the Department of Electrical Engineering and
Computer Sciences. Her research interests are in the general area of
signal processing and its applications to images and video, and
biomedical data. She has been a consultant to a number of industrial
organizations, holds 4 U.S. patents, and is the co-author of the
book, ``Oversampled A/D Converters'' with Soren Hein.
Ms. Zakhor was a General Motors scholar from 1982 to 1983, received
the Henry Ford Engineering Award and Caltech Prize in 1983, was a
Hertz fellow from 1984 to 1988, received the Presidential Young
Investigators (PYI) award, IBM junior faculty development award, and
Analog Devices junior faculty development award in 1990, and Office of
Naval Research (ONR) young investigator award in 1992. She is
currently a member of the technical committee for image and
multidimensional digital signal processing.
