Anil K. Jain (January 21, 1946 – November 14, 1988) was an Indian-American electrical engineer and Professor of the Department of Electrical Engineering and Computer Science at the University of California, Davis, known for his contributions on "two-dimensional stochastic models for images provided a firm theoretical foundation for a number of algorithms of spectral analysis, adaptive image estimation and image data compression", including work on transform coding for image compression and block-based motion compensation for video compression in particular.
Born in India, Jain received a bachelor's degree in electrical engineering in 1967 at the Indian Institute of Technology in Kharagpur, and a master's degree in 1969 and Ph.D. in 1970 from the University of Rochester. He had conducted his doctoral research at the University of Southern California under guidance of Richard Bellman.
After graduation Jain continued as postdoctoral fellow and later assistant professor in the department of Electrical Engineering and in the Image Processing Institute of the University of Southern California. In 1974 he joined the faculty of the State University of New York at Buffalo, and in 1978 back in California he became Professor at the University of California.
In 1983 Jain received the IEEE Donald G. Fink Prize Paper Award.
In 1988 Jain was recognized as a Fellow of the IEEE.
Jain's research interests ranged from "digital and image processing, computer vision, fast algorithms, real time digital systems architecture to stochastic processes and communication theory."
