Abstract
Wide-angle retinal images are synthesized from multiple fundus photographs (45 degree view) to provide a general view of the fundus. Fundus photographs contain distortion because they represent the projection of a three dimensional curved surfaces on to a two dimensional plane. A technique of making seamless blood vessel joints from several incongruous blood vessels in joint parts is proposed. The evaluation test on our technique and the overlay synthesis technique was executed to 1177 blood vessels. Our technique succeeded in the connection of 307 blood vessels (26%) which were not connected in the overlay synthesis. This method is therefore very promising for the automatic assembly of retinal blood vessel joint processing.
