4. CONCLUSIONS
The results show that the introduced parallel-sequential model
based on Newton's equations of motion and attracting forces
between edges may be a promising approach to real-time stereo
processing. The algorithm gives the right disparities in most
image points but there remain errors. Therefore, new efforts are
necessary to enhance the quality of the approach. Some ideas
for improvement are the following: First, far - field forces
should be introduced. Secondly, the assumed force law (16) —
(21) must be optimized or changed. When the right position
Xmax(i Jj) is reached then the external forces should reduce to
zero in order to avoid oscillations which are small but not zero
now.
Finally, it must be mentioned that the model can be extended to -
the non-epipolar case introducing coordinates y(i’,j) and forces
acting in y — direction.
