title: A new approach for detecting the position of retinal vessels and calculating their diameter on the basis of dynamic spectral analysis.
abstract: Fast adaptive algorithms were used for the detection of retinal vessels and for pre-processing the signals. By using different methods of dynamic spectral analysis, the local frequency of the vessels was determined. On this basis a method of calculating the diameters of the vessels was constructed; it is robust in relation to disturbances in the domain of the edges.
