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.
