  Dear all,

ndimage has find_object and label functions to find and cluster objects 
above a certain threshold.
I wanted to know if that happens in one pass through the data? There is 
an algorithm called the lutz algorithm (lutz 1979: 
http://comjnl.oxfordjournals.org/cgi/reprint/23/3/262) which only needs 
one pass through the data. I

If this is already implemented in scipy I wouldn't bother my summer 
student to implement it, if it isn't I would implement it and also make 
it available.
