In this paper, we introduce a multi-modal graphical model to address the problems of semantic segmentation using 2D-3D data exhibiting extensive many-to-one correspondences. Existing methods often impose a hard correspondence between the 2D and 3D data, where the 2D and 3D corresponding regions are forced to receive identical labels. This results in performance degradation due to misalignments, 3D-2D projection errors and occlusions. We address this issue by defining a graph over the entire set… CONTINUE READING
