Dense optical flow which adheres to a brightness constancy assumption, a gradient constancy
assumption, and a discontinuitypreserving spatiotemporal smoothness constraint.
Computes dense optical flow optical using pyramidal approach with square regions and a locally exhaustive search.
This is HornSchunck's well known work [1] for dense optical flow estimation.
Pyramidal implementation of HornSchunck [2] based on the discussion in [1].

Base class for pyramidal dense flow algorithms based on IPOL papers.
Computes dense optical flow optical using pyramidal approach with square regions and a locally exhaustive search.
