Laser marks detection from fundus images

Abstract

Eye diseases such as diabetic retinopathy may cause blindness. At the advanced stages of diabetic retinopathy further disease progression is stopped using laser treatment. Laser treatment leaves behind marks on the retinal surface that causes misbehaviors in automated retinal diagnostic system. These laser marks hinders the further analysis of the retinal images so it is desirable to detect laser marks and remove them to avoid any unnecessary processing. This paper presents a method to automatically detect laser marks from the retinal images and present some results based on the performance evaluation.
