This work describes a parallelizable optical flow estimator that uses a modified batch version of
the Self Organizing Map (SOM). This gradient-based estimator handles the ill-posedness in motion
estimation via a novel combination of regression and a self organization strategy.
The aperture problem is explicitly modeled using an algebraic framework
that partitions motion estimates obtained from regression into two sets, one (set Hc) with estimates
with high confidence and another (set Hp) with low confidence estimates. The self organization step
uses a uniquely designed pair of training set (Q=Hc) and the initial weights set …
