K. R. Rao is a 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 landmark publication, N. Ahmed, T. Natarajan, and K. R. Rao, "Discrete Cosine Transform", IEEE Transactions on Computers, 90–93, Jan 1974.

Education
Rao received a B.S. in Electrical Engineering (E. E.) from the College of Engineering, Guindy, affiliated with the University of Madras, India in 1952. In 1959, he received his M.S.E.E degree from University of Florida in 1959 followed by an M.S.NuE from the University of Florida in 1960. He received the Ph.D. degree in E. E. from the University of New Mexico, Albuquerque in 1966.
Work at UTA
Rao has been with the University of Texas at Arlington since 1966. He is currently a professor of electrical engineering, and the director of the Multimedia Processing Laboratory. He also teaches undergraduate courses on Discrete Signals and Systems and Fundamentals of Telecommunication systems. He also teaches graduate courses on Digital Video Coding, Digital Image Processing, Discrete Transforms and Multimedia Processing.
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 and 1/2 months – (Australia, India, Japan, Korea, Singapore and Thailand). He has conducted workshops/tutorials on video/audio coding/standards worldwide. He has supervised several students at the Masters (115) and Doctoral (33) levels. He has published extensively in refereed journals and has been a consultant to industry, research institutes, law firms and academia.
In 2011, Dr Rao reached an academic milestone, supervising his 100th Graduate Student.
He has been a plenary/keynote speaker in several international conferences.
He is a Fellow of the IEEE. He is a member of the Academy of Distinguished Scholars, UTA. He was invited to be panelist for the 2011 NSF Graduate Research Fellowship Program (GRFP), with service on the Electrical Engineering Panel. He was a panelist for the US EPA STAR fellowship program, 14–15 March 2013, Chantilly, VA and also in 2015.
Discrete cosine transform
He, along with two other researchers, N. Ahmed and T. Natarajan, introduced the discrete cosine transform (DCT) in 1975 which has since become very popular in digital signal processing. DCT, INTDCT, directional DCT and MDCT (modified DCT) have been adopted in several international video/image/audio coding standards such as JPEG/MPEG/H.26X series and also by SMPTE (VC-1) and by AVS China.
Publications
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), and Discrete Cosine Transform-Algorithms, Advantages, Applications (Academic Press, 1990).
Some of his books have been translated into Japanese, Chinese, Korean and Russian and also published as Asian (paperback) editions (also as e-books).
The book Video coding standards: AVS China, H.264/MPEG-4 Part10, HEVC, VP6, DIRAC and VC-1, (with D. Kim and J.J. Hwang) Springer was published in 2014. Translated into Chinese and Spanish.
