24-6 画像の多重解像度解析を利用した電子透かし方式

抄録

We present in this paper a novel method of digital watermark using multiresolution analysis of image. In this method, we embed watermark in the multiresolution components of image by using a controlled quantization process. Experimental results show that the proposed method gives the watermarked image of better quality and is robust against JPEG coding.
