Abstract :
In the present paper we propose a new algorithm for planar facets segmentation of sequences of uncalibrated images in order to recover 3D models of complex scenes. This is performed using a two-step algorithm. First a robust and regularized dense disparity field is computed under the epipolar geometry constraint. The resulting field is segmented according to homographic models using an iterative Delaunay triangulation
