Abstract
A fundamental assumption made in formulatingoptical-flow Mgorithms is that motion at any point in an imagecan be represented as a single pattern undergoing a simpletranslation: even complex motion will appear as a uniformdisplacement when viewed through a sufficiently smM1window. This assumption fails in a number of common sitnations.For example, transparent sttr[aces moving pastone another yield two motion components at each point.More important., the assunption fails along the...Keywords
