考虑出生率、死亡率、迁移率及居民年龄分布的人口预测程序(Population forecast program considering several factors including fertility, mortality, migration rates and age structure)

说明：  关于半色调编码计算全息图的信息隐藏Matlab程序的说明： 算法实现主程序为CGHwatermark； 位相恢复函数为phaseSL； 用计算全息记录已知振幅和位相的复波前函数为Hologen； 半色调编码函数为AMhalftone； 嵌入信息的提取直接调用Matlab自带的FFT2函数； 主程序的函数调用关系如下 读入宿主信息和水印信息-----------phaseSL--->Hologen--->AMhalftone(完成嵌入)--->FFT2（提取水印信息） 主程序结果保存于holo&mark文件夹 对算法鲁棒性测试的程序： 1. 对于剪切操作 Cliptest 结果存放于cliptest文件夹 2. 对于缩放操作 zoomtest 结果存放于zoomtest文件夹 3. 对于旋转操作 rotatetest 结果存放于rotate文件夹 4. 对于滤波操作 filtertest 结果存放于filtertest文件夹 5. 测试算法的时间效率 timetest 6. 分析嵌入信息后图像质量与参数alpha，tao的关系 msetest(err)

这个文章说明了格雷算法在心电信号处理上的应用(The paper proposes a learning algorithm for real-time analyzing the gray relations between templates and test electrocardiogram (ECG) signal patterns. Without analyzing relations between the test ECG pattern and every template in the database for the recognition, several training patterns for the learning algorithm are chosen from an ECG waveform database with patient diagnosis information, and then the training result is used to analyze the test ECG.)

Image Encryption based on the RGB PIXEL Transposition and Shuffling Abstract — Privacy is one of the key issues information Security addresses. Through encryption one can prevent a third party from understanding raw data during signal transmission. The encryption methods for enhancing the security of digital contents has gained high significance in the current era of breach of security and misuse of the confidential information intercepted and misused by the unauthorized parties. This paper sets out to contribute to the general body of knowledge in the area of cryptography application and by developing a cipher algorithm for image encryption of m*n size by shuffling the RGB pixel values. The algorithm ultimately makes it possible for encryption and decryption of the images based on the RGB pixel. The algorithm was implemented using MATLAB.
