Disparity estimation using a region-dividing technique and energy-based regularization

摘要: A two-stage algorithm is proposed for locating smooth and detailed disparity vector fields in a stereo image pair. The con- sists of hierarchical estimation using region-dividing technique edge-preserving regularization. dis- parity increases the efficiency reliability process. At second stage, are regularized with an energy model that produces while preserving discontinui- ties resulting from object boundaries. minimization problem ad- dressed by solving corresponding partial differential equation finite-difference method. Experiments show provides accurate spatially correlated vari- ous types images, even case images large displacements. © 2004 Society Photo-Optical Instrumentation Engineers.
