matlab图像处理实例详解chap7——图像分割技术(matlab image processing examples explain chap7- Image Segmentation)

利用低通、带阻FIR以及IIR技术对心电图上附加的白噪声、高斯噪声等进行滤波还原操作（内附心电图数值样品）。(We use low-pass, band stop FIR and IIR technology to filter and restore the additional white noise and Gauss noise on ECG.)

本压缩包是用于实验的载体图像和要嵌入的图像，仅供参考使用(The compressed package is used in the experiment to be embedded in the carrier image and the images used for reference only)

matlab中对ofdm系统进行仿真和分析的全系统模型，暂时部门模型有待大家优化！(matlab ofdm systems in the simulation of the entire system model and analysis, all the temporary sector model to be optimized!)

说明：  横截面为矩形的无限长槽由三块接地导体板构成，槽的盖板直流电压100v，求矩形槽的电位分布(A infinite long slot, with rectangle cross-section, consists of three grounded conductive plate and one coverplate with 100 voltage. Please give the potential distributions inside slot )

用于场地污染土壤、地下水等环境介质中各类污染物对当地居民的健康风险评价(Health Risk Assessment for the site contaminated soil, groundwater and other environmental media of various pollutants on the local residents)

数值方法：雅克比、高斯赛德尔、超松弛迭代法matlab编程(Numerical methods: Jacobian, Gauss Seidel, over relaxation iterative method matlab programming)

The plane stress analysis refers to the problems where the thickness of the structure is very small compared to other dimensions of the structure in the XY plane. The plane stress problem is a 2D problem. The stresses in the z direction are considered to be negligible,
 
0, the stress-strain compliance relationship for an isotropic material becomes,

这是一种整流电路，可以将相位相差120的三相交流电变换为直流，变化方法用到了电机控制中的坐标变换，SVPWM算法，方法比较新颖。(a kind of circuit which can convert three_phase AC voltage to DC voltge)

谱线增强器的代码，里面包含最陡下降法的实现，是华中科技大学出版的现代数字信号处理课后题3.16的答案，对理解谱线增强器和最陡下降法的实现有很大帮助。(Line enhancer code, which contains the implementation of the steepest descent method, is published by the Huazhong University of Science after-school modern digital signal processing, the answer to question 3.16, to understand the line enhancer and the implementation of the steepest descent of great help .)
