在本文中,我们提出了一种数字图像的可逆水印技术。在我们的上下文中,可逆性是指水印检测器恢复原始图像的能力。该技术基于在图像直方图中引入“间隙”的变换函数。 “间隙”用于对水印进行编码。一些实验表明可以实现相对较高的嵌入率。对于一组测试图像,我们在 PSNR 级别为 45-50 时获得了每像素 0.06 到 0.6 位的嵌入率。
In this paper we present a reversible watermarking technique for digital images. In our context, reversibility refers to the ability to restore the original image by the watermark detector. The technique is based on a transformation function that introduces 'gaps' in the image histogram. The 'gaps' are used to encode the watermark. Several experiments revealed that a relatively high embedding rate may be achieved. For a set of test images we obtained embedding rates between 0.06 and 0.6 bits per pixel at PSNR levels of 45-50.
