Viewpoint invariant 3D landmark model inference from monocular 2D images using higher-order priors
Found in: Computer Vision, IEEE International Conference on
By Chaohui Wang, Yun Zeng,Loic Simon,Ioannis Kakadiaris,Dimitris Samaras,Nikos Paragios
Issue Date:November 2011
pp. 319-326
In this paper, we propose a novel one-shot optimization approach to simultaneously determine both the optimal 3D landmark model and the corresponding 2D projections without explicit estimation of the camera viewpoint, which is also able to deal with misdet...
Segmentation of building facades using procedural shape priors
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Olivier Teboul, Loic Simon, Panagiotis Koutsourakis, Nikos Paragios
Issue Date:June 2010
pp. 3105-3112
In this paper we propose a novel approach to the perceptual interpretation of building facades that combines shape grammars, supervised classification and random walks. Procedural modeling is used to model the geometric and the photometric variation of bui...
