Research
I have always been excited about building intelligent systems that work. I draw inspiration from natural sciences, and my ideas revolve around computer vision, machine learning, robotics and, systems. Currently, I'm learning about the geometric and physical structure of our world to augment next generations of computational intelligence.

Saliency Guided Image Warping for Unsupervised Domain Adaptation
Shen Zheng★, Anurag Ghosh★, Srinivasa Narasimhan
Winter Conference on Applications of Computer Vision(WACV), 2025
[Website][Paper][Code]
Oversample salient object regions by warping source-domain images in-place during training while performing domain adaptation. Improve adaptation across geographies, lighting and weather conditions, is agnostic to the task, domain adaptation algorithm, saliency guidance, and underlying model architecture.

Learned Two-Plane Perspective Prior based Image Resampling for Efficient Object Detection
Anurag Ghosh, N Dinesh Reddy, Christoph Mertz, Srinivasa Narasimhan
Computer Vision and Pattern Recognition Conference(CVPR), 2023
[Website][Paper][Code]
A learnable geometry-guided prior that incorporates rough geometry of the 3D scene (a ground plane and a plane above) to resample the images for efficient object detection. This significantly improves small and far-away object detection performance while also being more efficient.

Exploiting Tradeoffs in Resource Constrained Vision
Novel methods for improving trade-offs at different levels of vision system abstractions. We considered constraints like real-timeness, network latency/bandwidth, inter-process contention, onboard compute, power, heat and battery considerations.

Smartphone-based Driver License Testing
Watch Microsoft CEO Satya Nadella explain the project!
Read about our work on PM Awards Innovations Coffee Table Book! (Extracted here)
Deployed in multiple states/10+ cities in India, automatically testing hundreds of thousands of drivers at a low-cost with >99% accuracy (test verified by human operator). See Overview and Dashboard.
Instead of prohibitively expensive (>150,000$) overhead pole-mounted camera infrastructure to estimate car trajectories and judge driver manuevers, we use sub-500$ smartphones and additionally get driver state monitoring for free (face verification, mirror scanning, distraction and seatbelt checks).

Analyzing Racket Sports From Broadcast Videos
Piloted with ESPN/Star Sports at Premier Badminton League, watched by tens of millions in South East Asia.
Do we really need half a million dollars for HawkEye to understand players? Our End-to-end framework automatically tags broadcast sport videos in near-real time. Our analysis shows a single camera suffices for mining rich and actionable player data, instead of relying on existing cumbursome multi-camera setups or sensors. It is used for live broadcast visualizations.
