FieldsElectrical Engineering

Kamisetty Ramamohan Rao was an Indian-American electrical engineer. He was a professor of Electrical Engineering at the University of Texas at Arlington (UT Arlington). Academically known as K. R. Rao,[2] he is credited with the co-invention of discrete cosine transform (DCT), along with Nasir Ahmed and T. Natarajan due to their landmark publication, Discrete Cosine Transform.[3]

Education

Rao received a B.S. in Electrical Engineering (E. E.) from the College of Engineering, Guindy, affiliated with the University of Madras, n 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 had been with the University of Texas at Arlington since 1966. He was a professor of electrical engineering, and the director of the Multimedia Processing Laboratory. He also taught undergraduate courses on Discrete Signals and Systems and Fundamentals of Telecommunication systems. He also taught graduate courses on Digital Video Coding, Digital Image Processing, Discrete Transforms and Multimedia Processing.

He had been an external examiner for graduate students from universities in Australia, Canada, Hong Kong, India, Singapore, Thailand and Taiwan. He was a visiting professor at universities in Australia, India, Japan, Korea, Singapore and Thailand. He conducted workshops/tutorials on video/audio coding/standards worldwide. He has supervised several students at the Masters and Doctoral levels. He published in refereed journals and has been a consultant to industry, research institutes, law firms and academia.

He was 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 during 2013 and 2015 in Chantilly, Virginia.

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.
