We enhance existing structured light phase shifting methods by using trigonometric moments.

Snapshot Difference Imaging using Correlation Time-of-Flight Sensors

Clara Callenberg, Felix Heide, Gordon Wetzstein, Matthias Hullin
ACM Transactions on Graphics 36(6) (Proc. SIGGRAPH Asia), 220:1--220:10, 2017.

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.

Proc. IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2016.

We show that using multi-frequency time-of-flight measurements, five different white materials can be distinguished on a per-pixel basis.
