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.
