I am using scipy.ndimage.filters.maximum_filter to find out the local maxima with the code like this:

neighborhood = ndimage.morphology.generate_binary_structure(2,2)
fore_ground=scipy.ndimage.filters.maximum_filter(iobrcbr,neighborhood)
However, when I running in python it has error:"sequence argument must have length equal to input rank". Could you please help me to fix this error? I am new in scipy.
Thanks so much.
Kind regards,
Lotus
                I think you need to specify that neighborhood is the footprint argument of maximum_filter.  The second positional argument is size.  Try maximum_filter(iobrcbr, footprint=neighborhood).
