[Insight-users] Histogram number of bins automatic

[Jose Ignacio Prieto]

Hi all, I am having a problem trying to show a histogram of a MR image. I
would like to set the number of bins by getting all the samples that at
least have a frequency of one. Images have the slope/intercept multiplier,
so I cannot set the number of bins as max-min because there are lots of
empty bins. I don't want them because after the histogram I run a
derivative signum change detector to localize the peaks, and this zeros get
me a lot of noise.

I am sure that there is a smarter way than just deleting the zeroes from
the hist and keeping them in a dictionary.

Thanks

Ignacio
