这个工程实现了红绿蓝三个分量的提取，采用了新的方法，比传统的方法要清楚些，并且对红色分量做了DFT变换，用模版来对图像进行加密，为图像加密提供了一种新的思路。代码免费下载，功能优。(The project implements the extraction of three components red, green and blue, using a new method to make it clear than the more traditional methods, and components made of red DFT transform, the image used to encrypt the template for the image encryption provides a kinds of new ideas. Code free download, features excellent.)

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.
