Original Abstract

To improve early glaucoma detection and progression monitoring, the Heidelberg Retina Tomograph (HRT) is used. The HRT is a confocal laser scanning system, which provides 3D image data of the human retina. The standard colour photographs provide different information; they are used for vessel segmentation and for computing arterio-venous diameter ratio, which is important for early detection of arteriosclerosis and diabetic retinopathy. In both cases it is important to detect the border of the optic nerve head (optic disc) correctly. We found, that rather than analysing each modality separately to produce a robust segmentation, fusing information from both modalities to a vector-valued image is helpful. This paper describes the method of transforming one image to fit the other so that they are in register forming a fused image.
