A Novel Method for Low-contrast and High-noise Vessel Segmentation and Location in Venipuncture.
IEEE Transactions on Medical Imaging(2017)
Abstract
Blood sampling is the most common medical technique, and vessel detection is of crucial interest for automated venipuncture systems. In this paper, we propose a new convex-regional-based gradient model that uses contextually related regional information, including vessel width size and gray distribution, to segment and locate vessels in a near-infrared image. A convex function with the interval si...
