Structured Light is a well-known method for acquiring
3D surface data. Single-shot methods are restricted to the
use of only one pattern, but make it possible to measure even
moving objects with simple and compact hardware setups.
However, they typically operate at lower resolutions and are
less robust than multi-shot approaches. This paper presents
an algorithm for decoding images of a scene illuminated by a
single-shot color stripe pattern. We solve the correspondence
problem using a region adjacency graph, which is explicitly
designed for robustness against surface color variations.
