適応量子化ウェーブレット変換電子透かしの絵画画像への適応

Abstract

The digital image watermarking is studied for both copyright protection and content authentication and needed to be better able to survive image processing operations and to be less degradation of picture quality. The characteristics of the watermark scheme is depends on the property of contents. This work deals with the image watermarking of the oil painting arts. The watermarking schemes based on the wavelet transform have many utilization for the digital image contents because it is able to consider the human vision system. This paper reports findings in the experiments of the image watermarking scheme based on wavelet transform for the oil painting arts.
