Free-Form Mesh Tracking : a Patch-Based Approach
In this paper, we consider the problem of tracking nonrigid surfaces and propose a generic data-driven mesh deformation framework. In contrast to methods using strong prior models, this framework assumes little on the observed surface and hence easily generalizes to most free-form surfaces while effectively handling large deformations. To this aim, the reference surface is divided into elementary surface cells or patches. This strategy ensures robustness by providing natural integration domains over the surface for noisy data, while enabling to express simple patch-level rigidity constraints. In addition, we associate to this scheme a robust numerical optimization that solves for physically plausible surface deformations given arbitrary constraints. In order to demonstrate the versatility of the proposed framework, we conducted experiments on open and closed surfaces, with possibly non-connected components, that undergo large deformations and fast motions. We also performed quantitati...
