Flash-Splat: 3D Reflection Removal with Flash Cues and Gaussian Splats
Mingyang Xie, Haoming Cai, Sachin Shah +4
We introduce a simple yet effective approach for separating transmitted and reflected light. Our key insight is that the powerful novel view synthesis capabilities provided by mode…
CodedVO: Coded Visual Odometry
Sachin Shah, Naitri Rajyaguru, Chahat Deep Singh +2
Autonomous robots often rely on monocular cameras for odometry estimation and navigation. However, the scale ambiguity problem presents a critical barrier to effective monocular vi…
CodedEvents: Optimal Point-Spread-Function Engineering for 3D-Tracking with Event Cameras
Sachin Shah, Matthew Albert Chan, Haoming Cai +5
Point-spread-function (PSF) engineering is a well-established computational imaging technique that uses phase masks and other optical elements to embed extra information (e.g., dep…
TiDy-PSFs: Computational Imaging with Time-Averaged Dynamic Point-Spread-Functions
Sachin Shah, Sakshum Kulshrestha, Christopher A. Metzler
Point-spread-function (PSF) engineering is a powerful computational imaging techniques wherein a custom phase mask is integrated into an optical system to encode additional informa…
Interpretable Disentangled Parametrization of Measured BRDF with -VAE
Alexis Benamira, Sachin Shah, Sumanta Pattanaik
Finding a low dimensional parametric representation of measured BRDF remains challenging. Currently available solutions are either not interpretable, or rely on limited analytical…
