Re: [WM]: Brighter images on Stirmark



Hello,
 
The following is my comments on your question:
 
No any problem about your computer.  Actually, all images get "brighter" after the stirmark attacks in my previous testing.
 
If your watermarking scheme is robust to intensity change. This problem makes a little affect on the test results of your algorithm.
 
If possible, you can choose Checkmark to test your method. There is more than 380 attacked images after implementing Checkmark, including JPEG and JPEG2000 lossy compressions, and various geometric attacks. You can download this benchmark in the official website.
 
Good luck for your research.

Hello ,

            I am a master student of Signal Processing from Brazil. I am using StirMark to test the robustness on my watermark scheme for my Thesis but I noticed that , even images such as JPEG with 100% quality.

            Is it something the program is supposed to do? Is this a problem with my computer? Can I change something in the .INI files to stop this from happening?

            Any help would be greatly appreciated.

                     ;    Thanks in advance.
