WebApr 26, 2024 · It appears to be that OpenCV uses pixel distance of 1 for the original image grid, and a pixel distance of (OLD_SIZE / NEW_SIZE), thus here 5/3 and 5/4, for the new image grid. Moreover, it aligns both grids at the center point. Thus, OpenCV's deterministic sampling algorithms can be visualized as follows: Visualization 5x5 to 3x3 ...
