CONTINUOUS 3D-LABEL SEMI-GLOBAL MATCHING FOR SATELLITE STEREO
We present Continuous 3D-Label Semi-Global Matching (CoSGM), a new dense stereo matching algorithm for satellite stereo. CoSGM overparameterizes the disparity map as an array of local planes, so it can regularize the first-order smoothness of the estimated disparity. Furthermore, the algorithm can p...

| Summary: | We present Continuous 3D-Label Semi-Global Matching (CoSGM), a new dense stereo matching algorithm for satellite stereo. CoSGM overparameterizes the disparity map as an array of local planes, so it can regularize the first-order smoothness of the estimated disparity. Furthermore, the algorithm can produce a dense normal map beside the disparity map. We show experimentally that CoSGM could achieve denser depth maps with comparable accuracy to traditional semi-global matching algorithms. |
