Mailman 3 Slow operation of nd_image.generic_filter - NumPy-Discussion

14 Oct 2004


      Hi all,
Could it be that the execution of the following function lasts more than 25 seconds, for an array of shape (256, 480)?
...
def myFunc(anArray, winSize=5):
    return numarray.nd_image.generic_filter(\
                input=anArray,
                function=lambda win: win.mean(),
                size=winSize,
                mode='constant')
...
Python 2.3, numarray 1.0 (XP, P4)
Regards,
Alban
