17-6 DCTを用いた電子透かし手法の電力分布と埋め込み位置の関係性(第17部門画像符号化2)

抄録

This paper investigates Relationship of the position of watermark embedding and power distribution of digital watermarking method using DCT. We found that there is a correlation between detection accuracy and the position of watermark embedding corresponding to the power distribution of the image.
