Drusen characterize the age-related macular degeneration. Automatic procedures for their identification have been recently developed. In this paper a cellular neural network based algorithm for drusen identification in fundus photograph is proposed. The algorithm is composed by different image processing steps: noise reduction, histogram normalization and a novel procedure of adaptive segmentation. The algorithm has been validated by using images provided from an ophthalmic medical center
