Reconstructing three-dimensional structure and motion is often decomposed into two steps: point feature correspondence and three-dimensional reconstruction. This separation often causes gross errors since correspondence relies on the brightness constancy constraint that is local in space and time. Therefore, we advocate the necessity to integrate visual information not only in time (i.e. across different views), but also in space, by matching regionsrather than points -using explicitdoi:10.1007/s00371-003-0202-6 fatcat:kozugtvwrvc6zdnjhckcuwxwca
