Distortionless_Data_Hiding
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.

线性调频信号是一种雷达常用的电磁波信号
线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标距离信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)
