Figure 7From: An FPGA-based processing pipeline for high-definition stereo videoIllustration of hierarchical, local, window-based disparity estimation. The left subfigure depicts the image pyramid. The image is iteratively downsampled by a factor of 2 on each stage. The right subfigure illustrates the search: the initial search is performed on the lowest resolution (stage 2 in this example). The determined disparity is subsequently refined in a very small search window on all higher resolutions.Back to article page
