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.)

Transforming images from the spatial domain to frequency domain using FFT and DCT, also it includes transforming to the Cepstrum domain.
