thanks for that one Chuck..

i have seen similar normailzations in most image processing code..what
exactly is the purpose of such normalization?before making images
these values will have to be reprocessed to get the pix

thanks Chuck..
i found the norm as you advised and then found newul=ul/norm

hi
i came across some image processing code in java and tried to
duplicate the operation on an ndarray.the array is supposed to contain
pixel values of a gryscale image generated by the program. however the
code does some accumulation operation as below to obtain a value
'norm'
ul=array(([],[.
