N2 - This paper presents a processor architecture for a robust road-extraction algorithm using stereo images. The road-extraction method estimates a projective-transformation matrix H that represents the geometrical features of road regions. The road region can be robustly extracted using Sum of Absolute Differences (SAD) between one image and a transformed image of the other one. To accelerate the projective transformation, dedicated multipliers are employed. A dynamically reconfigurable architecture for robust estimation and SAD-based extraction is presented. For image size 720 × 480, the execution time on the proposed processor is 0.05 seconds whereas that on a microprocessor is 2.5 seconds.
