First Claim
1. An image registration method implemented by an image analysis apparatus for determining a registration vector between two selected images of a group of at least three related images, the method comprising;
- a. determining a set of registration vectors, each being between a respective pair of images in the group;
b. determining, from the set of registration vectors, at least one composite registration vector leading from one selected image to the other selected image via at least one image other than the selected images;
c. determining an optimized registration vector, being the average of a plurality of registration vectors selected from;
i. the registration vector between the selected imagesii. the at least one composite registration vector.

Abstract
Methods for the registration of images typically assume that there are only two images, an assumption that is not always valid. By using the remaining images to obtain a choice of paths between two selected images, the transformation between the two can be determined with greater accuracy by averaging those paths. When averaging the paths, greater weight can be given to paths whose accuracy is known or reasonably believed to be greatest. Iteration of the process may be possible, where the available computation power is available.
