Matlab: Copyright protection of images using reversible watermarking

I need to implement Chrysochos’ reversible watermarking technique for the copyright protection of images by: -inserting invisible and reversible watermarking in a set of natural images; -attacking*/editing watermarked images; -extracting the watermark; -checking the watermark’s robustness extracted in attacks; -restoring the original image (if not possible to restore exactly the original one after an attack, show the difference (error)). I need tables and graphs for testing the algorithm’s performances in regards to the watermarked images’ quality and the robustness against different attack types *(adding different types of noise; high pass filter, low pass filter, median filter, jpeg compression, cutting regions from the image). // The code needs to be well commented. I started to write the code with the first step in Chrysochos’ technique but it needs work. If it’s not possible to continue what I started, it can be done from scratch.
