| http://www.w3.org/ns/prov#value | - This block based information may be used to get a motion vector for an entire object (or part of one) by detecting which pixels in each of the blocks belong to a given object and averaging them to deduce the motion vector(s) of that object. (An object may have more than one vector, e.g. a person walking will have limbs moving differently to the body).
