Skinning Artefacts Correction by Geodesic Regularization

We propose a method for correcting skinning artefacts caused by Linear Blend Skinning algorithm of triangular mesh object, based on loss that involves the calculation of geodesics distances between all its points to minimize distortion in its shape.

One crucial point is the usage of the Heat Method for the calculation of the geodesic distances based on the realization that its pipeline is fully differentiable, in a similar manner which was introduced for the first time in the LIMP paper}.

Our method is fast, modular and yields great improvement in terms of shape distortion compared to the original input.
