Optic Flow Estimation

Extended global variational approach by a Finite Element discretization (FEM) for Optic Flow estimation.
 

See application examples that can be addressed by this approach (link).
 

The extension of a global variational Optic Flow estimation covers the following properties:

• dense and smooth displacement vector fields by a globally convex variational ansatz,
• better numerical accuracy by
• a discretization of the differential equations based on Finite Elements (FEM),
• a multi-resolution approach,
• extended applicability compared to the classical approach:
• only two images of a time-sequence are necessary,
• the time-gap between images may be comparable large,
• the approach can still be applied on bigger pixel displacements.
