ARC Colloquium in conjunction with Computer Vision for Robotics Workshop

Speaker:Prof. Dr. Marc Pollefeys
Seminar Date:25/11/2016
Seminar Venue:NUS School of Computing, Lecture Theatre 19 (LT19)
ARC Colloquium Talk: Semantic 3D Reconstruction While purely geometric models of the world can be sufficient for some applications, there are also many applications that need additional semantic information. In this talk I will focus on 3D reconstruction approaches which combine geometric and appearance cues to obtain semantic 3D reconstructions. Specifically, the approaches I will discuss are formulated as multi-label volumetric segmentation, i.e. each voxel gets assigned a label corresponding to one of the semantic classes considered, including free-space. We propose a formulation representing raw geometric and appearance data as unary or high-order (pixel-ray) energy terms on voxels, with class-pair-specific learned anisotropic smoothness terms to regularize the results. We will see how by solving both reconstruction and segmentation/recognition jointly the quality of the results improves significantly and we can make progress towards 3D scene understanding.

There will be time for interaction with the speaker at the end of the seminar. Light refreshment will be served.
