Witryna15 sie 2024 · I know Otsu is often/usually used in papers, but that doesn't mean it's good or the best. It might mean that it worked okay for their images and it was easy since it's a built-in threshold. I find that it's often not good because it's best for images that have a nice bimodal histogram where the splitting threshold is rather obvious.
