NAME
     mlibImageMoment2Fp - second moment

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

     mlibstatus mlibImageMoment2Fp(mlibd64 *moment, const mlibimage *img);


DESCRIPTION
     The  mlibImageMoment2Fp()  function  computes  the  second
     moment of each channel in a floating-point 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.


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
