WitrynaImage rectification requires: the raw image (in this case, the jpegs) ground control points; The raw image doesn't need to have any projection data (indeed, I'd say shouldn't have, because if it's already georeferenced then a projection transform is the way to go). A ground control point is a location within an image for which the map ... Witryna31 sie 2010 · Stereo rectification is the determination of two image transformations (or homographies) that map corresponding points on the two images, projections of the …

WitrynaStereo image rectification projects images onto a common image plane in such a way that the corresponding points have the same row coordinates. This process is useful for stereo vision, because the 2-D stereo correspondence problem is reduced to a 1-D problem. As an example, stereo image rectification is often used as a preprocessing …

WitrynaIn this paper, we propose a Cross-Image Semantic Consistency guided Rectifying (CISC-R) approach for semi-supervised semantic segmentation, which explicitly leverages the labeled images to rectify the generated pseudo labels.
