Abstract

Abstract. The identification of retinal drusen is important in the diagnosis of Age-Related Macular Degeneration (AMD). This is normally undertaken through visual inspection of retinal colour images; a time consuming, resource intensive, process. In this paper an automated approach is proposed to support AMD screening. The fundamental idea is that instead of detecting the physical existence of drusen in the retina, representative patterns of retinal images (with or without drusen) are extracted in the form of histograms. Labelled exemplar histograms are then stored in a “case based”. New, “unseen ” examples are then classified by comparison with this case base and analysed for drusen using a Dynamic Time Warping (DTW) comparison process. Evaluation using the proposed approach has produced results that are both interesting and promising. 1
