Varun Ramakrishna --- Research

Research Summary

My research interests are at the intersection of computer vision, machine learning and optimization. My research goal is to develop autonomous systems to enable machines to understand and reason about human action and behavior allowing for richer interaction and seamless control. With this view, my current research focuses on detecting, tracking and reconstructing human pose from images and monocular video sequences.
