>>> And the relevant portion in imtools.py is:
>>> def histeq(im,nbr_bins=256):
>>>      """ Histogram equalization of a grayscale image. """
>>>
>>>      #get image histogram
>>>      imhist,bins = histogram(im.flatten(),nbr_bins,normed=True)
>>
>>
>> This is the call, but where is histogram? If it is in imtools are you sure

><function histogram at 0x10b0c0ed8>
