I am trying to write a code for median filter using scipy
the following is my code

from numpy import *
import ImageFilter
from scipy import *
import scipy.signal as signal
img = file('girl.png','rb').read() 
imgDest=signal.medfilt(img)
f1 = file( 'pygirl.png').write(imgDest)

I get the following error on running this code

Traceback (most recent call last):
  File "medfilt.py", line 6, in ?
    imgDest=signal.medfilt(img)
  File "/usr/lib/python2.4/site-packages/scipy/signal/signaltools.py", line
232, in medfilt
    return sigtools._order_filterND(volume,domain,order)
ValueError: data type must provide an itemsize


Can any one help please...:,(:,(
