Webb16 nov. 2012 · I have tried histogram-based segmentation. The problem with this approach is that the values of pixels surrounding the right-most cluster are most similar to the pixels of the left-most cluster, resulting in a "halo" around the right-most cluster. – Richard Nov 15, 2012 at 18:02 Have you tried bwboundaries, or bwlabel? They may … Webb7 apr. 2024 · More Answers (1) Use histcounts as direct solution instead. The data are inside the histogram but you've got to go "handle diving" to retrieve them if you didn't save the object handle when called it; if you did then see the 'Properties' section of the doc for it (link to in the 'See Also') section. All in all, it's easier to just use histcounts.
