85 results about "Face space" patented technology

Face space is a theoretical idea in psychology such that it is a multidimensional space in which recognizable faces are stored. The representation of faces within this space are according to invariant features of the face itself. However, recently was theoretically demonstrated that faces can be stored in the face space according to their dynamic features as well, and that in this case the resulting space exhibits a twofold structure.
