数学在数字图像处理中的研究及应用，包括家是变分法、偏微分方程等-Mathematics in the digital image processing research and applications, including home is the calculus of variations, partial differential equations, etc.

基于有限元的偏微分方程求解，并以漫射方程为例详细介绍了求解的推导过程-This report introduces the solution of PDE based on finite element method.

关于SFS算法的介绍，介绍了近些年来SFS方法的发展现状，将SFS算法划分为四种类型：演化和偏微分方程(PDE)方法、最优化方法、局部化方法以及线性化方法。同时，分析了各种SFS算法的特点，并对SFS技术的进一步发展趋势进行了展望。-Introductions of SFS algorithm, this paper introduces the development status of SFS method in recent years, the SFS algorithm is divi
