摘要： A method of processing a blood vessel image is provided. The method includes (a) sharpening an original blood vessel image using a Gabor filter in consideration of various directions and thicknesses of blood vessels included in the blood vessel and (b) detecting edges according to a change in brightness in a blood vessel domain and a non-blood vessel domain of the original blood vessel image and the blood vessel image on which the Gabor filtering step is completed, using an edge extraction method based on a first-order differentiation or second-order differentiation.
