dc.description.abstract | Wavelet tree based watermarking algorithms are generally using the energy difference among grouped wavelet coefficients for invisible watermark embedding and extraction. According to the cryptanalysis of wavelet tree quantization (WTQ) scheme, its robustness has been proven weak and modified wavelet tree quantization (MWTQ) is developed consequently. However, MWTQ needs the wavelet tree group data as the extra information and MWTQ is not blind for watermark extraction. Therefore, a novel wavelet tree watermarking using double wavelet tree energy modulation is proposed in this study. This study has performed intensive comparison for the proposed scheme with WTQ, WTGM and MWTQ under various signal processing attacks. The experiment results demonstrate that the proposed technique yields better performance with higher degree of robustness than WTQ. | en_US |
