1. A method for determining a likelihood that a first object captured in a first image and a second object captured in a second image are the same object, the method comprising: capturing the first image from a first viewpoint, wherein the first object is in the first image; capturing the second image from a second viewpoint, wherein the second object is in the second image; determining, using a processor, a first likelihood that a first visual feature on the first object and a second visual feature on the second object are the same visual feature; determining, using the processor, a second likelihood that a dimension of the first object and a corresponding dimension of the second object are the same; and determining, using the processor, a final likelihood that the first object and the second object are the same object based at least partially upon the first likelihood and the second likelihood.
