The code implements the Watermark Embedding module of the following paper:

J. Tian, "Reversible Watermarking by Difference Expansion", ACM Multimedia and Security Workshop, December 2002.

Embedding can be performed in the horizontal and vertical directions iteratively any number of times.

Final results in terms of PSNR are reported along with results of each iteration.

Please upload the decoder.m file if you have one.

How do we detect the watermark which is embedded here and if detected how to extract?
Is there a code for the extracting algorithm?
