NAME
     mlib_ImageMoment2 - second moment

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_ImageMoment2(mlib_d64 *moment, const mlib_image *img);


DESCRIPTION
     The mlib_ImageMoment2() function computes the second  moment
     of each channel in an image.


     It uses the following equation:

                     1     w-1 h-1
       moment[i] = ----- * SUM SUM img[x][y][i]**2
                    w*h    x=0 y=0


PARAMETERS
     The function takes the following arguments:

     moment    Pointer to  moment  array,  where  length  is  the
               number of channels in the image.


     img       Pointer to an image.
