how to get the second largest bin in histogram
Hi,
I want to get the second largest bin in hisogram, do you have any idea how to do this? Delete the largest bin is not a desireble solution I think, because it will make a chao in hisogram, like when you try to get the index of second largest bin, and if you delete something, the true index will be +1 or -1.
I think I can do something like reorder the histogram by using the inscreasing result of each bin, but not using the primal bins ordering.
Or I could also try to find something similar to GetMInMaxValue, which is only for C but not for C++, and get the pointer to an array and set all of them as NaN, then try to calcHist again and do minMaxLoc.minMaxLoc.

Thank you.
