ihybrid
figS2
Example of four reconstructed hybrids, used in the validation test, from a face pair and the information sampling strategies. We extracted the local or global information from one face of the pair (via the respective filters) and the complementary information from the other face of the pair. The combination of the spatial frequency bands extracted via the filter provided the reconstructed information for a given identified face and a given sampling strategy. It is worth noting that the striking difference in face identification (i.e. identifying Brad Pitt vs. William H. Macy) is relying on a very small difference on the pixel space.
