Abstract

The diffusion of digital content is very fast in today's technology. The velocity of gathering data might cause unlawful distribution of content. The major problem in content authorization is the robustness of methodology. Since frangible methodologies result unauthorized content access quicker, more robust solutions are essential for copyright protection. Watermarking technology is considered as a robust solution for copyright protection and authentication. In watermarking, quality of the image is a challenge. Applying a watermark on a medical image might cause corruption in original image, which leads to misleading content. The proposed copyright protection mechanism includes Quadtree algorithm which finds a region of non-interest to apply watermark on medical image in Discrete Wavelet Domain to provide authentication of the content without altering region of interest. Furthermore, in this paper, the visual quality of watermark implemented medical images and sample values are also discussed with the experimental results as well.
基于离散小波变换域的四象限医学图像鲁棒水印算法
在当今的技术中,数字内容的传播速度非常快。收集数据的速度可能会导致内容的非法分发。内容授权的主要问题是方法的健壮性。由于脆弱的方法导致未经授权的内容访问更快,因此更健壮的解决方案对于版权保护至关重要。水印技术被认为是一种强大的版权保护和认证解决方案。在水印技术中,图像的质量是一个难题。在医学图像上应用水印可能会导致原始图像的损坏,从而导致误导内容。提出的版权保护机制包括四分树算法,该算法在离散小波域中找到一个不感兴趣的区域对医学图像应用水印,在不改变感兴趣区域的情况下对内容进行认证。此外,本文还讨论了医学图像水印的视觉质量和样本值,并结合实验结果进行了讨论。
