K. R. Rao is a full professor of electrical engineering at The University of Texas at Arlington, UT Arlington. He is credited with the co-invention of discrete cosine transform (DCT), along with N. Ahmed and T. Natarajan due to their benchmark publication, “N. Ahmed, T. Natarajan, and K. R. Rao, "Discrete Cosine Transform", IEEE Trans. Computers, 90-93, Jan 1974.”
Professor Rao received the Ph. D. degree in electrical engineering from The University of New Mexico, Albuquerque in 1966. Since 1966, he has been with the University of Texas at Arlington where he is currently a professor of electrical engineering. He, along with two other researchers, introduced the Discrete Cosine Transform in 1974 which has since become very popular in digital signal processing. He is the co-author of the books “Orthogonal Transforms for Digital Signal Processing” (Springer-Verlag, 1975), Also recorded for the blind in Braille by the Royal Institute for the blind. “Fast Transforms: Analyses and Applications” (Academic Press, 1982), “Discrete Cosine Transform-Algorithms, Advantages, Applications” (Academic Press, 1990). He has edited a benchmark volume, “Discrete Transforms and Their Applications” (Van Nostrand Reinhold, 1985). He has coedited a benchmark volume, “Teleconferencing” (Van Nostrand Reinhold, 1985). He is co-author of the books, “Techniques and standards for Image/Video/Audio Coding” (Prentice Hall) 1996 “Packet video communications over ATM networks”(Prentice Hall) 2000 and “Multimedia communication systems” (Prentice Hall) 2002. He has coedited a handbook “ The transform and data compression handbook,” ( CRC Press, 2001). Two books in final stages: Digital video image quality and perceptual coding, (with H.R. Wu),Taylor and Francis (Dec. 2005). Introduction to multimedia communications: applications, middleware, networking, (with Z.S. Bojkovic and D.A. Milovanovic), Wiley, (Nov. 2005). Some of his books have been translated into Japanese, Chinese, Korean and Russian and also published as Asian (paperback) editions. He has been an external examiner for graduate students from Universities in Australia, Canada, Hong Kong, India, Singapore, Thailand and Taiwan. He was a visiting professor in several Universities -3 weeks to 7 and1/2 months- (Australia, Japan, Korea, Singapore and Thailand). He has conducted workshops/tutorials on video/audio coding/standards worldwide. He has supervised several students at the Masters and Doctoral levels. He has published extensively in refereed journals and has been a consultant to industry, research institutes, law firms and academia. He is a Fellow of the IEEE.
