ACM Transactions on Graphics 36(4) (Proc. SIGGRAPH), 35:1--35:11, 2017. 4D Imaging through Spray-On Optics

Raindrops on a window heavily distort the view of the scene. We show that a fully calibrated 4D light field can be recovered from a single photograph taken under such adverse conditions.

Snapshot Difference Imaging using Correlation Time-of-Flight Sensors

ACM Transactions on Graphics 36(6) (Proc. SIGGRAPH Asia), 220:1--220:10, 2017. Snapshot Difference Imaging using Correlation Time-of-Flight Sensors

Computation of image differences is a key operation in computational imaging. We use time-of-flight sensors to perform this operation in a single shot, and discover some remarkable features.

ACM Transactions on Graphics (Proc. SIGGRAPH), 34 (4), 2015. Doppler Time-of-Flight Imaging

A new computational imaging system that captures metric radial velocity information per pixel -- think of a huge array of traffic speed guns that use light instead of radar.

Low-Budget Transient Imaging using Photonic Mixer Devices
