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
