A device, method and system for automatic montage of segmented retinal images

摘要

A device and a method of automatic global matching of a plurality of images to provide a substantially consistent planar representation of a fundus is disclosed. The device for automatic global matching of a plurality of images to provide a substantially consistent planar representation of a fundus includes a local matching module and a global matching module. The local matching module is adapted to locally match a pair of overlapping images. As part of locally matching the images, the local matching module is adapted to provide a best offset vector for the images based upon a matching of features from overlapping portions of the images. The global matching module is adapted to globally match at least a triplet of locally matching pairs of images whose best offset vector sum is substantially zero.
