Research on Clone Algorithm Applied in Edge Detection of Retinal Vessels

摘要

A marginal clone algorithm is proposed in order to make edge detection of retinal vessels image have better edge continuity and less detection points. It is applied in edge detection of retinal vessels with a combination of edge connectivity and noise removal algorithm based on analyzing image edge cloning theory and algorithms. Simulation results show that the edge image detected by the algorithm has solved problems of traditional edge discontinuities and too much noise. Moreover, it has better edge recognition performance.
