Combining Sebastian and Jae-Joon's suggestions, I have something that might work:
>>> timeit numpy.bincount(array.flat) 10 loops, best of 3: 28.2 ms per loop This is close enough to video-rate... And I can then combine bins as needed to get a particular bin count/range after the fact. Thanks, everyone, Zach _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
