mlib_ImageCrossCorrel(3MLIB) mediaLib Library Functions mlib_ImageCrossCorrel(3MLIB)
NAME
mlib_ImageCrossCorrel - cross correlation
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageCrossCorrel(mlib_d64 *correl, const mlib_image *img1,
const mlib_image *img2);
DESCRIPTION
The mlib_ImageCrossCorrel() function computes the cross-correlation between a pair of images.
It uses the following equation:
1 w-1 h-1
correl[i] = ----- * SUM SUM (img1[x][y][i] * img2[x][y][i])
w*h x=0 y=0
where w and h are the width and height of the images, respectively.
PARAMETERS
The function takes the following arguments:
correl Pointer to cross correlation array on a channel basis. The array must be the size of channels in the images. correl[i] contains
the cross-correlation of channel i.
img1 Pointer to first image.
img2 Pointer to second image.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
