摘要
现有的可见水印技术将水印嵌入到整幅图像或图像的任意位置,没有考虑图像的具体内容,但对于许多应用而言,图像的某些特定区域(如感兴趣区域)比其他区域更重要。该文提出了一种感兴趣区域的自适应可见水印技术,在用户选定的感兴趣区域嵌入可见水印。实验结果表明:水印半透明地呈现在用户选定的感兴趣区域,为感兴趣区域提供了更好的保护。
Most existing visible watermark techniques embed watermarks into the entire image or stochastic position without taking the image content into account. But for many applications, certain portions of an image are more important than the other regions, which are often called the regions of interest （ROI）. This paper proposes an adaptive visible watermark technique in ROI. The watermark is embedded into the ROI. Experimental results have shown that watermarked images meet the requirements of visible watermarks quite well. ROI does receive better protection.
