DCT变换图像压缩
- 基于DCT变换的图像压缩处理,压缩比可自己调整(Image compression processing based on DCT transform)
DCT - Open Source
- DCT Implemetation using FFT.
Image Compression with DCT
- 基于DCT的图像压缩的简单例子,方便新手学习。(DCT based image compression simple example, easy for beginners to learn.)
MATLAB DCT水印
- 在matlab平台下对DCT水印算法进行仿真实现。(In Matlab platform, the DCT watermarking algorithm is simulated.)
matlab实现DCt
- 用MATLAB实现DCT水印算法。信号经过DCT后,从空间域变换到频域。是一种正交变换的方法。是图像处理中应用即为广泛的傅氏变换中一种特殊的情况(被展开函数是实偶函数,再离散化,即为离散余弦变换)。 同傅氏变换一样,有正反两种变换。(DCT watermarking algorithm is implemented with MATLAB.)
DCT变换

DCT变换图片压缩
- 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 ment
