NAME
       mlib_ImageMoment2_Fp - second moment

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageMoment2_Fp(mlib_d64 *moment, const mlib_image *img);

DESCRIPTION
       The mlib_ImageMoment2_Fp() 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 MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
