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’, 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.
