On a consistency issue in multiresolution stereo

The authors address an important problem in the multiresolution (pyramid) approach to the correspondence problem in computational vision: the consistency between the domain and range (disparity) pyramids. Consistency guarantees the validity of pyramidal implementation. The authors investigate some previous approaches in stereo vision and present a general framework in multiresolution stereo. Simulations on natural stereo pairs exhibit results that are superior with this consistency check.<
