模糊神经和软计算 时间序列 预测 神将网络 模糊控制(Fuzzy neural and soft computing time series prediction)

说明：  算法计算n=1到N的Fourier系数偶次谐波抽样点上的直流分量(err)

雷达仿真的源程序，功能齐全，添加了界面，易于使用。(Radar Simulation of the source, fully functional, add the interface easy to use.)

提出了一种鲁棒的多水印嵌入与检测算法,该算法基于小波域,且提取水印时不需要原始图像,保护了原始图像的安 全。在该多水印算法中,提出并使用了一种将密码学和常规的数字水印制作方法- - - 叠加法和量化调制法,有机结合起 来的新的方法,在水印嵌入时,不同的水印,生成与该水印相关的不同的密钥,在进行水印的提取时,用不同的密钥和待测的 图像提取出相应的水印。通过将密钥向第三方注册,可以获得对原始图像的所有权。(A robust multi-watermark embedding and detection algorithm, the algorithm based on wavelet domain, and extract the watermark without the original image, protect the safety of the original image. In the multi-watermarking algorithm, will be presented and used a conventional cryptography and digital watermarking production method--- superposition method and quantify the modulation method, combine the new method, the watermark embedding different watermark, associated with the watermark generating different keys, making extraction of the watermark when tested with a different image key and the corresponding extracted watermark. By the key to a third party registration, can be obtained ownership of the original image.)

可以对自定义体模或者临床数据进进行fbp重建-fbp (Custom phantom or clinical data into the the fbp reconstruction-fbp)

一个基于jakes模型的瑞利衰弱频道的matlab程序，很好用。(A jakes model based on Rayleigh fading channel C++ program, easy to use.)

matlab几个常用程序，用来学习神经网络编程练习(matlab several commonly used procedures used to study neural network programming exercises)

说明：  在matlab中开发了一种如何使算法收敛更快，精度更高的算法，效果明显(developed in the Matlab how a convergence algorithm faster and more precise algorithms, obviously)
