Retinal image registration based on binary vessel tree
 Klímová, Jana ; Kolář, Radim (referee) ; Harabiš, Vratislav (advisor)
This bachelor’s thesis treats of binary retinal image registration. The images were photographed with a fundus camera and consequently a vessel tree has been segmented. Two binary images of the same retina have been acquired. The aim of this thesis is to acquaint with and describe methods of retinal image segmentation and registration and to suggest a process of binary image registration. The image registration is based on binary vessel tree, which is segmented with an already existing computer programme. One of the images is referred to as the reference or source and the second image is referred to as the transformed or sensed. Two image registration methods have been proposed. The first one is based on 2D transformation and image subtraction. The sensed image is rotated and translated to the position where the vessel tree is overlaid and the images are geometrically aligned. The second method uses detection of blood vessel bifurcation in the binary retinal images.
