摘要:
提出一种基于MPEG-4码流的视频水印算法.该算法将离散余弦变换(discrete cosine transform,DCT)与运动矢量相结合.对水印图像进行离散小波变换,将小波变换后水印图像的低频系数嵌入到视频序列I帧DCT变换后的低频系数中,而将小波变换后水印图像的中频系数嵌入到B帧的运动矢量中.实验证明,该算法既保证水印的不可见性,又可增强水印的嵌入强度和鲁棒性.
Abstract:
A new digital video watermarking algorithm based on MPEG-4 stream was proposed.The watermark signal was transformed into wavelet coefficients.The low frequency band in wavelet coefficients was embedded into the low frequency band in DCT coefficients of I frame.The motion vector of B frame was designed to host the mid-frequency band in wavelet coefficients.The experimental results demonstrate that the robustness and intensity of watermark is improved with desirable invisibility.
