| 摘 要： | 本文利用双树复小波变换(DTCWT)的多方向选择性和平移不变性,结合人眼视觉特征和MPEG运动编码原理,分析视频纹理复杂的运动区域来嵌入水印。仿真实验结果表明,该算法在抵抗加性Gaussian噪声、高压缩比的MPEG压缩编码、帧重组、帧平均和丢帧等攻击方面具有很好的鲁棒性。

| Abstract: | In this paper, we unify the attractive properties of shift invariance and good directional selectivity of dual tree complex wavelet transform (DTCWT), analyze motion and complex texture block for embedding according to human visual system (HVS) and MPEG motion encoding theory. Simulation results show that the algorithm is robust to AWGN, MPEG coding at high compression ratio, frame drop, frame average and frame swap. |
