Color Image Watermarking For Copyright Protection
Watermarking is an effective and potential method for copyright protection in digital audio, image and video data. One of the media is digital image, where it can be copied and displayed widely while still maintaining the quality. Protections to these images become more and more important. One...

| description | Watermarking is an effective and potential method for copyright protection in
digital audio, image and video data. One of the media is digital image, where it can be
copied and displayed widely while still maintaining the quality. Protections to these
images become more and more important. One of the simple methods is to hide the data
and then get back the data by owner itself, with certain secret key. The main objective
of my project is to find out which color model representation is suitable apply the digital
image watermarking for copyright protection. One of the watermarking techniques in
frequency domain is applied. At the same time, the robustness of the implemented
algorithm to the common image processing operation, example, filtering attack, noise
attack, rotation attack, and lossy JPEG compression. Some images are used in the
testing. Detailed description of every resulted image and watermark is show out in this
report. Quality evaluation to the images is carried out and comparison is made. The
quality metrics used in this project is PSNR. |
