Detection of visible vessels of vocal folds in videolaryngostroboscopy images

The clinical diagnosis of voice pathologies is based on examination of structural defect of the vocal folds with video laryngostroboscope. Clinical studies show that pathologies not only cause vocal fold mulfunction but also effect the visual characteristics of blood vessels on the superior surface of vocal folds. In this article, we propose a novel system that extracts the vocal folds vessels in the images acquired during routine videolaryngostroboscopy and help physicians in presenting the relationship between blood vessel defect and vocal fold pathologies.
