说明：  此算法为最小二乘参数估计的递推算法。运行后得到辨识参数：a1= -1.4981, a2= 0.7038, b1= 1.0476, b2= 0.4704。(The algorithm for the recursive least squares parameter estimation algorithm. After operation to identify the parameters: a1 =-1.4981, a2 = 0.7038, b1 = 1.0476, b2 = 0.4704.)

说明：  菲涅尔波带片设计 用菲涅尔波带片的方式设计衍射光学元件位相分布。(Fresnel zone plate design)

此程序能够完成对电容元件的几何特性自适应测量。(This program can complete the adaptive measurement of geometric characteristics of the capacitor element. )

Image Quality Assessment simple coding in Matlab

二次多项式拟合大地水准面，采用matlab编写的，关于拟合出来的图像感觉有些问题。。希望大家指正(Quadratic polynomial fitting geoid, using matlab prepared some questions about the fitting out of the picture feel. . I hope you correct)

Watermark A visible or invisible signature embedded inside an image to show authenticity or proof of ownership. The hidden watermark should be inseparable the host image, robust enough to resist any manipulations while preserving the image quality. Thus through watermarking, intellectual properties remains accessible while being permanently marked.
