The Gaussian Filter is one of the processing methods to smoothen images. Before detecting an object, this method is used as pre-processing, for eliminating useless detail, and connecting unnatural parts. We implemented a Gaussian Filter on FPGA, as that is the pre-processing system of the real time stereo vision system in this paper. The hardware implementation method saves the image in the Line Buffer...
A correction method for local stereo matching disparity images is an essential technology in stereo vision. We propose the hardware architecture for correcting a real-time disparity image. This method uses the similarity between the pixel of invalid disparity value and the neighboring pixels to estimate an alternative value for the invalid value. The experimental results showed that the proposed system...
