Abstract
This work describes two anisotropic optical flow inpainting algorithms. 
The first one recovers the missing flow values using the Absolutely 
Minimizing Lipschitz Extension partial differential equation (also 
called infinity Laplacian equation) and the second one uses the Laplace 
partial differential equation, both defined on a Riemmanian manifold. 
The Riemannian manifold is defined by endowing the plane domain with an 
appropriate metric depending on the reference video frame. A detailed 
analysis of both approaches is provided and their results are compared 
on three different applications: flow densification, occlusion 
inpainting and large hole inpainting.
