We present a method to improve surface reconstruction using color encoded structured light. A video camera is used to obtain a color encoded pattern projected onto the object using a projector. A multi-stage method is presented to reconstruct the surface from the captured pattern. It consists of
i) a robust edge detection step,
ii) a color decoding using feedback from previous stripes and
iii) a propagation step to detect errors and propagate detected stripes.
Using feedback and propagation we can reconstruct areas where regular color detection fails by bridging small gaps which happen due to illumination variations or noise. The reconstruction results are illustrated for human skin.
