| [objective] The boundary of retinal blood vessels is determined in a noisy background. [Methods] this project mainly aimed at the generation of directional pattern, the direction of noise reduction processing and other key technologies to study, to obtain a relatively complete blood vessel edge image, the use of image processing method for retinal blood vessel image parameters for qualitative and quantitative analysis. The edge extraction method based on directional filtering can effectively extract most blood vessels, and the correct rate is higher. [Conclusion] the extraction of retinal blood vessel edge is the specific application of edge detection, which is of practical.#$NLKeyword： the direction of the map, directional filtering, noise suppression |
