program

这个是一个基于matlab实现傅里叶变换的一个小的程序，共大家学习使用。(This is a matlab-based Fourier transform to achieve a small program, we were learning to use.)

this code is for genetic algorithm matlab

File to operate pilot plat from Matlab

说明：  关于Arnold的一种反变换新算法 本算法无需根据周期恢复原图 只要知道正变换的密钥即可(Arnold on a new algorithm for the inverse transform of the cycle of the algorithm does not need to know is as long as the original recovery key can transform)

提出了一种可抗 几何攻击的二值文本图像水印算法. 该算法基于DCT,它将二值图像的DCT、图像的视觉特征向 量和加密技术有机结合起来,在提取水印时不需要原始图像,是一种实用的盲水印算法(We propose a geometric attacks against Binary Text Watermarking Algorithm. The algorithm is based on DCT, it binary image DCT, the image of the visual feature vector and encryption technology combine in the watermark without the original image is a practical blind watermarking algorithm)

利用最小方差方法估计复正弦加白噪声得平稳信号的功率谱(After using the method of minimum variance estimate sine smooth white noise to the signal power spectrum)

張智星的MATLAB介紹，主要是學習MATLAB的應用，如何操作和模擬。(Zhang Zhi-sing introduction of MATLAB, mainly studying the application of MATLAB, how to operate and simulation.)

在文本框输入不同的参数，绘制得到相应的抛物曲线。(In the text box to enter different parameters to draw the corresponding parabolic curve.)

说明：  CRC校验的Matlab仿真，也可以认为是二进制除法。(CRC checksum of the Matlab simulation, it can be regarded as a binary division.)
