说明：  this code is usable for embed watermark into image

说明：  matlab 图像处理 使用噪声能量和图像一维自相关函数进行维纳滤波(matlab image processing and image noise energy use one-dimensional autocorrelation function of Wiener filter)

简单的采样，设计一个输入序列，实现其采样，绘出采样后的时域波形(Simple sampling design an input sequence, to achieve its sample, drawn after the time-domain waveform sampling)

The code implements the following paper: Guorong Xuan, Jiang Zhu, Jidong Chen, Shi Y.Q., Zhicheng Ni, Wei Su, "Distortionless data hiding based on integer wavelet transform" IET Electronics Letters, Volume: 38, Issue 25, page 1646- 1648, December 2002. (ISSN: 0013-5194) The watermark embedding and extraction modules have been implemented separately. The watermark embedding module embeds the watermark using bitplane compression in the integer wavelet transform domain. The watermark extraction module extracts the previously embedded watermark and restores the original image. A logo image is used as a watermark but can be replaced with any thing.
