Description: 这是我一个DSP实习，用汇编语言编实现离散余弦变换（DCT）的DSP程序设计。它有详细的设计流程、仿真结果，有完整的模块源码。其中有工程文件，和一个WORD文档，相信能让你清新的了解设计过程，掌握汇编设计离散余弦变换！-This is my internship a DSP using assembly language for the realization of discrete cosine transform (DCT) of DSP programming. It has a detailed design process, simulation results, with complete source code of the module. Among them, engineering documents, and a WORD document, I believe you can clean the design process to understand and master the design of discrete cosine transform compilation!

Description: 本人根据公式用VC++做出的DCT变换源码，解说清楚。转换矩阵8*8，计算结果与MATLAB计算结果比较，两者几乎一样(相差仅 0.001)，估计是计算误差，经过我的实践证明并不影响使用。-According to the formula I use VC++ source code to the DCT transform, to clarify. Conversion matrix 8* 8, the calculation results compared with the MATLAB calculation results, the two are almost identical (a difference of only 0.001), it is estimated that the calculation error, after I prove that the practice does not affect use.

Description: 在一个图像块中调整两个(或多个) DCT系数的相对大小。将描述一个使用数字图像作为载体的系统。在编码处理中，发送者将载体图像分成8×8的像素块，每一块只精确地编码一个秘密信息位。嵌入过程开始时，首先伪随机地选择一个图像块bi，用它对第i个消息比特进行编码。令Bi=D{bi}为DCT变换后的图像块。
在通信开始前，发送者和接收者必须对嵌入过程中使用的两个DCT系数的位置达成一致，让我们用(u1,v1)和(u2,v2)来表示这两个索引。这两个系数应该相应于余弦变换的中频，确保信息保存在信号的重要部位(从而使嵌入信息不容易因JPEG压缩而完全丢失

Description: 里面要求实现基于DCT变换的图片压缩程序，基本上复制以后就可以直接运行。值得一提的是，我里面直接调用了三个个外部的包，如果用eclipse编译器或者其他的话，需要在偏好设置中自行设置，否则会报错。具体设置可以自行百度，很简单的(It requires the implementation of image compression program based on DCT transform. After copying, it can run directly. It is worth mentioning that I directly call three external.Com packages, if I use eclipse compiler or other words, I need to set my preferences in my preferences settings, otherwise I will report errors. Specific settings can be self - Baidu, very simple)
