mlib_ImageMoment2_Fp - second moment
cc [ flag... ] file... –lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageMoment2_Fp(mlib_d64 *moment, const mlib_image *img);
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
The function takes the following arguments:
Pointer to moment array, where length is the number of channels in the image.
Pointer to an image.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
