I was just reading the latest draft of the DiPy paper and came across this name.  I had no idea what it meant!  It sounds cool, perhaps some ninja move?  But I really think it would help to use a much more descriptive function name, even if it is longer to type.  Something like ``threshold_median_otsu`` or ``select_median_otsu`` would allow us to add other similar methods later which fit into the same naming convention.  Also, when a person reads a code line with such a name, you know exactly what's happening under the hood (even if you are not a DiPy dev).
