利用Matlab语言开发的一种LSB最低有效位数字水印算法(Matlab language development using a least significant bit LSB watermarking algorithm)

说明：  完善网络结构将RBF网络的径向基换成小波函数，调整权值以及公式的变更， 可望在仿真结构中添加非奇异项以验证小波网络的辨识精度和能力，输入层加权值进行调整~..~(to improve the network structure of the RBF network replaced wavelet Radial Basis Functions, value and the right to adjust the formula change, the simulation structure is expected to add non-singular wavelet network to verify the accuracy and the ability to identify, input layer weighted value adjustments )

采用matlab程序 实现DCT水印源程序代码(DCT Watermark source code)

说明：  灰色理论的应用，是一种成语实现，用于预测数据。(Application of Grey theory is a kind of idiom to achieve, to predict the data.)

Data Encryption by Matrix Multiplication We will only use numbers 0 to 26 for the encryptive mathematics operation. Numbers from 1 to 26 are for letters from A to Z and 0 is for all non-letter characters. To minimize usage of numbers, all letters are converted to upper case. The original message is converted to number array according to the ASCII table and minus 64. We partition whole array into blocks of 8 numbers. The last block may be added several zeros. Then multiply each block by the an 8x8 matrix A which is invertible in Z27 to get cipher data. The decryption is the same process except to use its inverse matrix B. For good visual reading, we convert all non-letter characters to under score for the decryption.
