说明：  level set及PDE方法处理图形图像 包括三个部分：1、level set理论基础介绍；2、数值离散化方法 3、应用 每一部分配有详细的图表说明，并给出了多篇参考文献（其中很多涉及到“三维物体修复”）
(level set and PDE methods deal with graphic images of three parts: 1, level set introduce the theoretical basis 2, numerical discretization method 3, the distribution of each application has detailed description of the chart, and gives a number of references (many of them related to )
