Fast global non-rigid registration for mosaic creation

In this work we present a new registration method designed for image mosaicing of scenes containing non-planar surfaces. A global non-rigid deformation model may have a high number of parameters. To tackle this problem, we apply a registration framework combining deformation model based on triangular meshes and feature point registration. In the registration framework, since we formulate the energy function for achieving the global registration as a quadratic function, the optimum of the energy can be found very efficiently by solving sparse linear systems. We performed experiments to demonstrate the precision and efficiency of our method.
