Abstract :
In this work, it is presented functional hardware architecture for stereo processing with a modified census transform. Architecture is segmented in image rectification to avoid lens distortion, stereo processing with a modified Census transform and finally post processing using a propagation algorithm to correct false disparity values. Proposed architecture uses minimal hardware and memory requirement in a way that Spartan Low Cost FPGA is used for implementation.
