Retinal vessel segmentation using multi-scale textons derived from keypoints

The visual appearance of the retina in digital fundus images is an important indicator of eye disease and can be diagnostic of a range of more general issues relating to health and wellbeing. As such, fundus photography is also used in screening programmes for diseases such as diabetes and hypertension and the morphological properties of retinal vessels are reported in routine clinical and ophthalmological examinations. The projected increase in patients suffering from these disorders together with the tedious nature and high cost of manual examination has motivated research into computer assisted tools that can improve precision, consistency and throughput.
