Blood Vessel Segmentation of Retina Image Using Markov Model in Wavelet Domain

This paper concerns the scheme of blood vessel segmentation based on Markov model in wavelet domain. Two algorithm requirements, i.e. visible vein of blood and integrality is taken into account simultaneously for segmentation result. As for enhancement of blood vessel veins, Guided Filter is employed to ameliorate images of contrast ratio and sharpen vein details. After the pretreatment, retina images are extracted blood vessels. Based on DRIVE, STARE and FIRE data sets, simulation results are provided to demonstrate the applicability and effectiveness of the proposed segmentation method.
