Comparative Study of Retinal Vessel Segmentation Based on Global Thresholding Techniques

Comparative Study of Retinal Vessel Segmentation Based on Global Thresholding Techniques

Due to noise from uneven contrast and illumination during acquisition process of retinal fundus images, the use of efficient preprocessing techniques is highly desirable to produce good retinal vessel segmentation results. This paper develops and compares the performance of different vessel segmenta...
