说明：  粒子群优化算法(PSO：Particle swarm optimization) 是一种进化计算技术（evolutionary computation）。源于对鸟群捕食的行为研究。粒子群优化算法的基本思想：是通过群体中个体之间的协作和信息共享来寻找最优解．(PSO (Particle Swarm Optimization) is an evolutionary computation. It comes from studying the behavior of flocks of birds. The basic idea of particle swarm optimization algorithm is to find the optimal solution through the cooperation and information sharing among the individuals in the group.)

说明：  用FFT做谱分析的实验代码，附有详细的实验说明和源代码以及对实验现象的分析(FFT spectrum analysis done using the experimental code, with detailed experimental descriptions and source code as well as the analysis of experimental phenomena)

在matlab 中多种方式的边缘提取。edge(matlab edge)

图片印刷字符的识别（可识别多种字体） 将Matlab工作空间路径设置为本文件夹 在Matlab命令窗口内输入： numCongnition( able1/01.jpg ) 通过改图片来对不同的图进行处理，其中able1,able2,able3三个文件夹分别对应三种字体 命令窗口输出要识别的字符，并且自动弹出中间处理过程窗口 也可以运行： num = pretreat( able1/01.jpg ) imshow(num) 直接得到预处理后的图片 再键入： getNumber(num) 得到字符输出 (Set the Matlab workspace path to this folder In the Matlab command window input: NumCongnition ( able1/01. JPG) Through change pictures to deal with different figure, including able1, able2, able3 three folders corresponding to three kinds of fonts Command window output to identify characters, and automatically process among popup Windows Can run: Num = pretreat ( able1/01. JPG) Imshow (num) Directly after preprocessing of images Type: GetNumber (num) Get the output character)

说明：  本案例研究的目的是开发一种简单而有效的半隐式傅里叶光谱算法，用于相位场晶体模型的变形研究(The purpose of this case study is to develop a simple and effective semi-implicit Fourier spectral algorithm for the deformation study of phase field crystal models)
