The Compressed Video Image Multiple Digital Watermarking Hiding Method Simulation
Based on the modified scrambling transformation,a hiding method of multiple digital watermarking of non-compressed video image is proposed.Firstly,wavelet transform is used to carry out multi-level decomposition for original video image,and chaos digital watermarking is superimposed in high-frequency wavelet coefficient with different levels of resolution ration.Then,inverse wavelet transform is carried out to generate watermarking image,and the transformation parameter based on queen scrambling transformation is selected as a secret key.Moreover,binary sequence of image embedding watermarking is transformed into gray value.Finally,the image is recovered according to inverse transformation of scrambling transformation.Simulation proves that the method can guarantee antiattacking of the digital watermarking of video image effectively.It has strong robustness.
