The present graph cut methods cannot be used directly for real time stereo matching
applications because of their recursive structure. Graph cut method is modified to
change its recursive structure so that making it suitable for real time FPGA (Field
Programmable Gate Array) implementation.
The modified method is firstly tested by MATLAB on several data sets, and the
results are compared with those of previous studies. Although the disparity results
of the modified method are not better than other methods&rsquo / , computation time
performance is better. Secondly, the FPGA simulation is performed using real data
sets. Finally, the modified method is implemented in FPGA with two PAL cameras
at 25 Hz. The computation time of the implementation is 40 ms which is suitable for
real time applications.
