Optical flow computation has already been done by a wide variety of methods
but still there are several of sources of error that cause inexact results. If the
monogenic phase vector is used instead of the intensity, the computation of the
optical flow becomes more robust against changes in lighting, thus the influence
of one source of error can be diminished. In this project three existing methods
for optical flow computation have been changed by substituting the intensity constraint
with the monogenic phase vector. These methods were the method of Horn
and Schunck, a combined method of Horn and Schunck and Lucas and Kanade
(CLG) and a method using a non-linearised constancy assumption. |
