CV

   I am interested in the intersection of computational photography and image processing.
How does a camera see colors compared to human eyes and brain?
How does motion affect what is seen by the camera?
Are these properties of cameras liabilities, or does being different from human eyes provide a complementary advantage?
Now Research Scientist at Meta (Facebook) Reality Labs
Computational Photography, On-device Computer Vision/AI
Before Research Scientist at Carnegie Mellon University
Image Science lab, Department of ECE
with Prof. Aswin Sankaranarayanan
Past M.S and Ph.D at Indian Institute of Technology Madras
Image Processing and Computer Vision lab, Department of EE
under the supervision of Prof. A.N. Rajagopalan and Prof. R. Aravind
