Claim One:
1. A method of stabilizing a series of retinal angiography images to provide a coherent serial display, said method comprising: locally matching each pair of overlapping images, said locally matching includes at least providing a best offset vector for the images, wherein the best offset vector is provided based upon a matching of features from overlapping portions of the images; globally matching at least a triplet of matching pairs of images, wherein pairs of globally matching images include locally matching pairs whose best offset vector sum is substantially zero; choosing a key image; aligning remaining images from the series of images to the key image, wherein said aligning comprises computing distortions between the key image and each of the other images; and computing corrective transformations to compensate for the distortions using one of: a free quadratic model, an affine model and a translation model, and rendering the other images according to the computed corrective transformations.
