ROI based embedded watermarking of mages

Hi everybody,

I am working on a project on digital watermark for an image based on ROI (region of interest).

The first step in this project is to separate ROI using roipoly or imfreehand or any other interactive way, and then considering RONI (region of non interest) and applying 3 level DWT using "Haar" wavelet. Where only RONI will be used for watermark embedding.

Please if any one can help with MATLAB code for separation of ROI out of cover image and prepare the RONI for other steps:

Many thanks in advance.

Is this the same question as http://www.mathworks.com/matlabcentral/answers/55565-medical-image-watermarking-and-cryptography-system?

My question is, if you have a medical image then you must have legal rights to use it so why can't you get the original non-watermarked version of it? Then you wouldn't have to worry about removing it.
