Experience

Research Intern May 2017 - August 2017
Samsung Display America Lab San Jose, CA
  • - Developed a new objective image fidelity metric that models the display and the Human Visual System.
  • - Goal: Evaluate visually lossless compression in Samsung displays.
Research Assistant January 2015 -
Video and Image Processing (VIPER) laboratory, Purdue University West Lafayette, IN, USA
Developed and used deep learning and computer vision techniques for:
  • - Precision Agriculture. Count, locate and segment plants in aerial images taken from drones using CNNs and GANs.
  • - Medical imaging. Segment endocardium in echocardiograms and estimate heart ejection fraction.
  • - Visual Surveillance. Count people from videos. Improved accuracy by incorporating crowdsourcing.
