Stripe boundary codes for real-time structured-light range scanning of moving objects
O Hall-Holt, S Rusinkiewicz - Proceedings of International Conference on Computer Vision, 2001

Spacetime faces: high resolution capture for modeling and animation
L Zhang, N Snavely, B Curless, SM Seitz - ACM Transactions on Graphics (TOG), 2004
For static scene, traditional binary coded sequence overtime is OK. However, when the scene moves, traditional methods fail. The spacetime solution works by estimating a linear local disparity window.
Thus, when the hand in the scene moves, the spacetime method works better,
The setting for spacetime face reconstruction,

High-speed 3-D shape measurement based on digital fringe projection
PS Huang, C Zhang, FP Chiang - Optical Engineering, 2002
Seperating the RGB channel of DLP projector to achieve the high-frequency of time-varing coded patterns.
Sinusoidal phase-shifting method. BW-camera works at 240Hz detecting each RGB phase(color filters are removed) for the decoding. Color-camera works at 60Hz to capture the surface color of target objects.
