Research

I am with the NEMESYS research group investigating and implementing region-of-interest (RoI) streaming for HD video. I was involved in the research, design and implementation of techniques for RoI identification, cropping, scaling, storage and retrieval. Currently I am working on virtual zoom and pan in live video feeds from a network of  cameras.

Earlier I worked as a Senior Research Engineer at the Motorola Labs in India (Applied Research). My work focused on in-router  video aware bandwidth management algorithms, differentiated routing in multi-channel MESH networks, video retrieval and caching based on physical surroundings. My research career kicked off as a Senior Software Engineer with the ProCurve networking division at Hewlett-Packard India.

Academic Background
  • Doctor of Philosophy (faculty of engineering) from  Indian Institiute of Science for the thesis titled "Information Theoretic Approach to Extractive Text Summarization".   
The research work describes information theoretic measures for extractive text summarization based on modeling sentence constructs as symbol occurrences. Methods described are purely statistical in nature augmented with hierarchical structures derived from WordNet dictionary. A mathematical formulation for the notion of "discrimination" was derived and used as an adaptive thresholding metric.
  • Master of Science (faculty of engineering) from  Indian Institiute of Science for the thesis  titled "Active Routers for Optimal Delivery of Streamed MPEG Packets under Low Bandwidth Constraints."
The thesis details design, implementation and performance of a Linux router optimized for streaming MPEG video in bandwidth constrained networks.
