img_one_correlation_coefficient

Source:

src/img/img_combine.c

Description:

Calculates correlation coefficient between two images.

Algorithm: 

	The correlation between two images is calculated and normalized as:

		           sum((image1 - avg1)*(image2 - avg2))

		CC = -------------------------------------------------

		     sqrt(sum(image1 - avg1)^2 * sum(image2 - avg2)^2)

	.

	Both images are converted to floating point.

	Only the first image is used.

Arguments:

Bimage* p1first image.
Bimage* p2second image.

Returns:

double correlation coefficient, -1 if not run.

Prototype:

double img_one_correlation_coefficient(Bimage* p1, Bimage* p2)
