Abstract
A method of vessel tracking has been developed for quantification of vessel diameters of retinal images. This method utilises twin Gaussian functions to model the distribution of grey level over a vessel cross section. The diameter of the vessel at the cross section can then be calculated using the functions. The variation of vessel diameter in the direction of vessel longitude axis has been described by a tracking technique based on parameters of modelled intensity distribution curves over every cross section. This enables us to obtain an average diameter over any length of a vessel and to develop more parameters for diagnosis and study of vascular diseases.
