Learning non-rigid 3d shape from 2d motion

Nettet15. jun. 2000 · The paper addresses the problem of recovering 3D non-rigid shape models from image sequences. For example, given a video recording of a talking person, we would like to estimate a 3D model of the lips and the full face and its internal modes of variation. Many solutions that recover 3D shape from 2D image sequences have been … NettetThis brief tutorial paper on Shape from Motion (SfM), the profound 3D object modeling method, focuses on mathematical background for the batch scenario. Error bounds for pixels with respect to depth change are derived to analyze the applicability of orthographic projection versus perspective projection.

NettetAbstract. We present a closed-form solution to the problem of recovering the 3D shape of a non-rigid inelastic surface from 3D-to-2D correspondences. This lets us detect and reconstruct such a surface by matching individual images against a reference configuration, which is in contrast to all existing approaches that require initial shape ...
