Hybrid retinal image registration using phase correlation

Popis výsledku v původním jazyce

This paper deals with registration of retinal images, which were taken by highresolution digital colour fundus cameras. The proposed method describes successful application of phase correlation method. It combines several basic steps - global correctionof shift, rotation and scaling, detection of landmarks, their correspondences and finally image registration using second-order polynomial model. The method is tested on two sets of images. The first set contains images from the diabetic patients where many retinal pathologies can disturb the registration process. The second set contains images from healthy subjects, which were acquired by different illumination conditions. The method was evaluated using four different criteria - tree objective and onesubjective. These criteria are also compared. The achieved registration accuracy of the landmarks position error is 1.13 and 0.93 pixels for respective image sets. Finally, the simple scheme for retinal pathology visualisation of register
