Automatic Adaptive Optics Retinal Images Montaging

Abstract

The adaptive optics images capture limited field of view. Nevertheless, the quantitativeretina assessment requires analysis over extended areas captured by images on various retina positions.The fully automated method for image registration and montaging is presented. The methodutilizes scale invariant feature transform (SIFT) for feature extraction from preprocessed images.The method is tested on 200 images of normal healthy patients. The montages of 20 eyes were createdand evaluated by normalized mutual information metrics and the results showed high alignmentaccuracy.
