It is accepted that digital watermarking is quite relevant in medical imaging. However, due to the special nature of clinical practice, it is often required that watermarking not introduce irreversible distortions to medical images. The electronic clinical atlas has such a need of "lossless" watermarking. We present two tailored reversible watermarking schemes for the clinical atlas by exploiting its inherent characteristics. We have implemented the schemes and our experimental results look very promising.
人们普遍认为数字水印在医学成像中具有重要意义。然而，由于临床实践的特殊性质，通常要求水印不会给医学图像带来不可逆的失真。电子临床图谱就有这种“无损”水印的需求。我们通过利用临床图谱的固有特性，为其提出了两种定制的可逆水印方案。我们已经实现了这些方案，并且我们的实验结果看起来非常有前景。
