CHASE-DB1 dataset for Vessel Segmentation

The CHASE_DB1 is a retinal vessel reference dataset acquired from multiethnic school children. This database is a part of the Child Heart and Health Study in England (CHASE), a cardiovascular health survey in 200 primary schools in London, Birmingham, and Leicester. The ocular imaging was carried out in 46 schools and demonstrated associations between retinal vessel tortuosity and early risk factors for cardiovascular disease in over 1000 British primary school children of different ethnic origin. The retinal images of both of the eyes of each child were recorded with a hand-held Nidek NM-200-D fundus camera. The images were captured at 30 degrees FOV camera. The dataset of images are characterized by having nonuniform back-ground illumination, poor contrast of blood vessels as compared with the background and wider arteriolars that have a bright strip running down the centre known as the central vessel reflex.
