Accelerated motion

Accelerated morion

With accelerated motion, the continuity equation of the optical flow can be extended as follows:

(f + at)∇g + gt = 0

1. Formulate the over determined linear equation system for the optical flow f and the acceleration a (4 parameters in 2-D images) with an approach similar to that in Section 14.3.2.
2. Show that it is impossible to determine the acceleration if the sequence contains only two images.
