A MPEG-2 Video Dual Watermarking Technique based on Temporal Modulation of Low-Frequency DCT Coefficients
碩士 === 中國文化大學 === 機械工程學系數位機電碩士班 === 101 === The low-frequency DCT coefficients of an image are relatively insensitive to geometric processing. In this paper, the low-frequency DCT coefficients of a full DCT domain are divided into several blocks, and the mean of the coefficients of each block is tem...
