SpinCam: High-Speed Imaging via a Rotating Point-Spread Function

no code implementations • ICCV 2023 • Dorian Chan, Mark Sheinin, Matthew O'Toole

High-speed cameras are an indispensable tool used for the slow-motion analysis of scenes.

Dual-Shutter Optical Vibration Sensing

no code implementations • CVPR 2022 • Mark Sheinin, Dorian Chan, Matthew O'Toole, Srinivasa G. Narasimhan

Visual vibrometry is a highly useful tool for remote capture of audio, as well as the physical properties of materials, human heart rate, and more.

Holocurtains: Programming Light Curtains via Binary Holography

no code implementations • CVPR 2022 • Dorian Chan, Srinivasa G. Narasimhan, Matthew O'Toole

Light curtain systems are designed for detecting the presence of objects within a user-defined 3D region of space, which has many applications across vision and robotics.

Efficient Non-Line-of-Sight Imaging from Transient Sinograms

no code implementations • ECCV 2020 • Mariko Isogawa, Dorian Chan, Ye Yuan, Kris Kitani, Matthew O'Toole

Non-line-of-sight (NLOS) imaging techniques use light that diffusely reflects off of visible surfaces (e. g., walls) to see around corners.
