Sexualp?dagogische (Re)Visionen will be analytically proven that the removal process plays role in reducing the interference between an original signal and a watermark to be embedded. This is simply based on the orthogonality of the DC signal and the AC signal. As a result, the process improves the ability of the right detection.作者: lanugo 時(shí)間: 2025-3-22 14:35
