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.
