I would probably walk in from the left and right sides one bin at a time until you find a local max in each case.

Walking to a local minimum *might* work. I can see it would
work in some cases. I might have too few pixels in some
cases to avoid minimums in areas that should be in the
same group. I probably could look for a minimum of
some specified "width" as I walked. I'll give it a try.

Thanks!
