Abstract

電子透かしは,透かしが埋め込まれた合成画像からもとの原画像に復元することが可能か否かで可逆電子透かしと非可逆電子透かしとに分類できるが,非可逆電子透かしは,医用目的等ある種のアプリケーションに対しては利用できない場合がある.本研究では,我々が先に提案した複数帯域のウェーブレット変換係数を用いた電子透かし方式に基づいた,可逆電子透かし方式を提案する.

Watermarking Methods are classified into two types. One is a reversible watermarking method which can restore to the original image from a watermarked one, and another is an irreversible watermarking method. However, an irreversible watermarking method cannot be utilized to some sort of application system such as a medical imaging system. In this paper, we propose a new reversible water-marking method based on a digital watermarking method using wavelet transform coefficients of several bands.
