摘要
主要研究在小波变换域中,基于图像特征的自适应可见数字水印嵌入处理技术。小波变换的多分辨率特性更适宜于人类视觉感知系统,不同分辨率层次的水印图像像素根据对应宿主图像像素的特征嵌入到宿主图像中。
The article discusses a kind of image-based adaptive visible digital watermarking treatment technology in discrete wavelet transform (DWT). The multiresolution of DWT resembles human visual perception system. The watermark is embedded into the host images based on the characteristics of host image's pixels.
