Active Safety Envelopes using Light Curtains with Probabilistic Guarantees
Siddharth Ancha, Gaurav Pathak, Srinivasa G. Narasimhan +1
To safely navigate unknown environments, robots must accurately perceive dynamic obstacles. Instead of directly measuring the scene depth with a LiDAR sensor, we explore the use of…

DTG-Restore: Training-Free Diffusion Refinement for Generative Video Super-Resolution
Hidir Yesiltepe, Koutilya PNVR, Gaurav Pathak +4
Recent progress in video diffusion models has enabled remarkable generative fidelity, yet leveraging these priors for restoration remains limited by the strong coupling between con…

Active Velocity Estimation using Light Curtains via Self-Supervised Multi-Armed Bandits
Siddharth Ancha, Gaurav Pathak, Ji Zhang +2
To navigate in an environment safely and autonomously, robots must accurately estimate where obstacles are and how they move. Instead of using expensive traditional 3D sensors, we…
