int compute_rms_image_difference
(
	const KJB_image *in1_ip,
	const KJB_image *in2_ip,
	double *rms_diff_ptr
);

DESCRIPTION

This routine computes the RMS difference between two images. Only valid pixel pairs are used. The result is returned in *rms_diff_ptr.

RETURNS

NO_ERROR on success and ERROR on failure, with an error message being set. The routine will fail if the two input images are different dimensions, or there is no valid pixel pair.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
