img_R_factor

Source:

src/img/img_combine.c

Description:

Calculates an R factor between two images.

Algorithm: 

	The difference between two images is calculated and normalized as:

		                      sum(image1 - image2)^2

		R = sqrt(-------------------------------------------------)

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

	Both images are converted to floating point.

Arguments:

Bimage* p1first image.
Bimage* p2second image.

Returns:

float R factor, -1 if not run.

Prototype:

float img_R_factor(Bimage* p1, Bimage* p2)
