Together with João Fayad and Lourdes Agapito we are trying to deal with the problem of reconstructing complex non-rigid objects. A face deforming can be approximated easily by a set of linear 3D model but, for instance, a flag waving in the wind is a different matter. For such problem, we are presenting a new framework for dealing with such complex shapes based on piecewise quadratic approximations of the deforming body. This video shows 3D modelling results from 2D images for two highly non-linear deformations:

These three slides schematically resumes the pipeline used for the 3D reconstruction:

Pipeline for Piecewise Reconstruction Step 1-2

Pipeline for Piecewise Reconstruction Step 3-4

Pipeline for Piecewise Reconstruction Step 5-6

This work will be presented this year in ECCV 2010. More information and the paper will appear soon in these pages.
