About Me
- [Longish Short Bio]
Sunil Kumar Kopparapu (Senior Member, IEEE; ACM Senior Member India - 2015) obtained his doctoral degree in Electrical Engineering from the Indian Institute of Technology, Bombay, India in 1997. His thesis "Modular integration for low-level and high-level vision problems in a multi-resolution framework" provided a broad framework to enable reliable and fast vision processing.
Between 1997-2000 he was with the Automation Group, Commonwealth Scientific and Industrial Research Organization (CSIRO), Brisbane, Australia working on practical image processing and 3D vision problems, mainly for the benefit of the Australian mining industry.
Prior to joining the Cognitive Systems Research Laboratory (CSRL), Tata Infotech Limited, as a Senior Research Member, in 2001, he was associated with the R&D Group at Aquila Technologies Private Limited, India, as an expert for developing virtual self line of e-commerce products.
In his current role as a Principal Scientist with the TCS Innovations Labs - Mumbai, he is actively working in the areas of speech, script, image and natural language processing with a focus on building usable systems for mass use in Indian conditions.
He has coauthored a book titled Bayesian Approach to Image Interpretation and more recently a Springer Brief on Non-linguistic Analysis of Call Center Conversation apart from several patents, journal and conference publications.
