Abstract:

Conditions are studied under which a perspective motion field can have multiple interpretations and present analytical expressions for the relationship among these interpretations. Furthermore, in most cases, the ambiguity in the interpretation of a motion field can be resolved by imposing the physical constraint that depth is positive over the image region onto which the surface projects.
