We introduce variational optical flow computation
involving priors with fractional order differentiations.
Fractional order differentiations are
typical tools in signal processing and image analysis.
The zero-crossing of a fractional order Laplacian yields
better performance for edge detection
than the zero-crossing of the usual Laplacian.
The order of the differentiation of the prior
controls the continuity class of the solution.
Therefore, using the square norm of
the fractional order differentiation of optical flow field
as the prior,
we develop a method to estimate
the local continuity order of the optical flow field at each point.
The method detects the optimal continuity order of optical flow
and corresponding optical flow vector at each point. |
