1. A method comprising: (a) specifying a first object class; (b) specifying a second object class; (c) generating a first object network, wherein each object of the first object network belongs to the first object class, wherein the first object network includes a first object that is linked to a first plurality of pixel locations; (d) generating a second object network, wherein each object of the second object network belongs to the second object class, wherein the second object network includes a second object that is linked to a second plurality of pixel locations, wherein all of the objects of the second object network are linked to a third plurality of pixel locations, and wherein the third plurality of pixel locations includes the second plurality of pixel locations; (e) generating a third object network by imprinting each object of the first object network into the second object network, wherein the third object network includes a third object that is linked to a fourth plurality of pixel locations, wherein the fourth plurality of pixel locations is a subset of the third plurality of pixel locations and is calculated from the first plurality of pixel locations; and (f) determining a characteristic of the third object by measuring the third object.
