摘要：
This paper addresses the issues in the development of automated system for the analysis of retinal angiographic images, providing focus on the segmentation of the blood vessels. Performance of three different Template Matching Algorithms are analyzed in respect of the detection of blood vessels in the retinal images for both gray-level and color images. The Gausian Matched Filter (GMF) and Binary Matched Filter (BMF) are used to detect the edges of blood vessels and capillaries of gray level images and also to reduce the noise. Kirsch Template Matched Filter (KMF) is used for same purpose in color images. The results obtained provide the complete vessle map, there by increasing the diagnostic ease of the ophthalmologist.
