Pattern encoding/decoding (I)
•A pattern is encoded when after projecting it onto a surface, a set of regions of the observed projection can be easily matched with the original pattern. Example: pattern with two-encoded-columns

•The process of matching an image region with its corresponding pattern region is known as pattern decoding à similar to searching correspondences
•
•Decoding a projected pattern allows a large set of correspondences to be easily found thanks to the a priori  knowledge of the light pattern
Pixels in red and yellow are directly matched with the pattern columns
