Quantum Cosine Transform Based Watermarking Scheme for Quantum Images被引量：4
《Chinese Journal of Electronics》2015年第2期321-325,共5页WANG Shen SONG Xianhua NIU Xiamu 
supported by the National Natural Science Foundation of China(No.61301099,No.61100187,No.61361166006);Heilongjiang Province Educational Department Funds of China(No.12521107)
A novel watermarking scheme for quantum image is proposed based on Quantum cosine transform(QCT). The cosine coefficients are extracted by executing QCT on quantum image. A dynamic vector for controlling embedding str...

A Color Image Watermarking Scheme in the Associated Domain of DWT and DFT Domains Based on Multi-channel Watermarking Framework被引量：3
《Chinese Journal of Electronics》2009年第4期665-670,共6页ZHENG Jiangbin ZHENG Jiangbin FENG Sha FENG Sha ZHANG Yanning ZHANG Yanning 
We propose a watermarking scheme based on the multi-channel watermarking framework, which is mainly used to resist geometric attacks. This watermark- ing scheme generates watermarking templates from one image transfor...

Image Watermarking Via Sequencing Wavelet Filters
《Chinese Journal of Electronics》2008年第4期649-654,共6页HUANG Zhuanqing JIANG Zhuhan 
We propose to watermark images based on wavelet filter banks by encoding the watermark bits into the choice of the filters, in contrast to the conventional watermarking schemes. Such filters are selected from differen...

A Rotation Scaling and Cropping Inavariant Second Generation Watermarking Scheme Based on Hough Transform被引量：2
《Chinese Journal of Electronics》2003年第1期126-131,共6页JIZhen ZHANGJihong XIAOWeiwei 
In this paper,a scheme which follows the seconde generation watermarking(2GW)paradigm is proposed.The goal of this proposed scheme is basically to increase the robustness against geometric attacks.The host image is de...
