Abstract: Curvelet transform is a multi scale transform that can represent the edges along curves much more efficiently.Retinal images play important roles in finding of some diseases in early stages, such as diabetes, which can be performed by comparison of the states of retinal blood vessels. Automated image processing has the potential to support in the early detection of diabetes, by detecting changes in blood vessel diameter and patterns in the retina. Proposed paper describes the development of segmentation methodology in the processing of retinal blood vessel images obtained using non-mydriatic color photography. Highly accurate identification of blood vessels for the purpose of studying changes in the vessel network that can be utilized for detecting blood vessel diameter changes associated with the path physiology of diabetes. There is a deficiency of missing some thin vessels is because of utilizing a simple thresholding method. My contribution is to implement a technique that will also be applicable for small length blood vessels.
