Research
I like building efficient, useful and impactful intelligent systems. My work span areas such as computer vision, machine learning, robotics and (mobile/distributed) systems. At CMU, I'm leveraging the inherent geometric and physical nature of our world to inform visual intelligence. Please find my past work below.

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]
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.

Honorable Mention, Streaming Perception Challenge, CVPR 2021. [Presentation at WAD]
Learning optimal tradeoffs instead of handcrafting heuristic functions is a more natural way to design complex real-time perception systems operating within severe resource constraints.

Streaming Video Analytics On The Edge With Asynchronous Cloud Support
Read about our work on Microsoft Research Blog!
Anurag Ghosh, Srinivasan Iyengar, Stephen Lee, Anuj Rathore, Venkat Padmanabhan
International Conference on Internet of Things Design and Implementation (IoTDI), 2023
[Paper]
Should we choose between offloading and on-device execution for Edge AI workloads? Our simple algorithm shows that a careful combination of the two approaches makes them complementary and achieve state-of-the-art performance.

Holistic Energy Awareness for Intelligent Drones
Srinivasan Iyengar, Ravi Raj Saxena, Joydeep Pal, Bhawana Chhaglani, Anurag Ghosh, Venkat Padmanabhan, Prabhakar T. Venkata
International Conference on Systems for Energy-Efficient Built Environments (ACM BuildSys), 2021
[Paper]
(Best Paper Runner-Up)
Holistically considering battery charecteristics and AI workload constraints for multi-drone flightpaths to develop an energy-aware scheduling system decreases energy consumed by 21.14% and mission times by 46.91% over state-of-the-art.

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 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.
End-to-end framework for automatic tagging and analysis of 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 can be used for live broadcast visualizations too.
