Title: Reconstruction meets recognition
Prof. Marc Pollefeys, Dept. of Computer Science, ETH Zurich

Abstract:
The two main goals of computer vision are to recognize the different elements of a scene and to reconstruct their 3D shape and spatial arrangement from images. In the past the reconstruction and recognition problems have mostly been approached separately. In recent years a few approaches have been proposed that use recognition to help reconstruction or vice-versa. In this talk we present the first approach that jointly performs 3D scene reconstruction and recognition. Our approach is formulated as a volumetric multi-class segmentation problem and solved using a convex relaxation method. A key element of our approach is that the interface between classes (e.g. building, ground, vegetation, air) have different anisotropic smoothness priors. We will show how our joint approach significantly improves the results.




Short bio:
