| 摘 要： | 为了有效地解决血管遮挡、噪声污染、光照不均、对比度小以及个体间差异大等视乳头图像分割中固有
的难题，提出采用基于图论的多相分段常数水平集ＭｕｍｆｏｒｄＳｈａｈ图像分割模型及其相应的图分割最优化方法。实验表明，该方法能够比经典的多相分段常数水平集ＭｕｍｆｏｒｄＳｈａｈ模型更快更精准地分割青光眼病人视乳头图像中的视杯和视盘形态。

| Abstract: | In order to solve the existing problems caused by blood vessels obscuration, noise pollution, illumination odds, low contrast, and inter-differences when one segments the optic cup and disk in optic nerve head images, this proposed to use graph min-cut method for multiphase Mumford-Shah Model. The tests demonstrate that the proposed method is more efficient and more accurate than piecewise constant level set method(PCLSM) for multiphase Mumford-Shah model. |
