围绕移动终端多媒体数据版权保护问题,在智能手持装置中引入Client—Service方法,将码书设计与水印嵌入分开.采用IEENNS搜索算法缩短编码时间,借助图像检索方法自动选择码书.设计系统分为两个子系统:一个是最优码书生成子系统,一个是自识别VQ子系统.实验结果表明,不仅能够提高码书生成质量与重构图像的质量,同时能够缩短编码时间,而且具有较强的鲁棒性.
This paper focuses on mobile multimedia copyright protection, and further presents the separate design i- dea of codebook design and embedding based on Client - Service model, respectively. It uses IEENNS search algo- rithm to reduce the coding time and automatically selects the codebook by image retrieval thinking codebook. This design system is divided into two subsystems: one is the generating system of the optimum codes and another is a self - identifying VQ system. The experimental results showed that it could not only improve the quality of codebook generation and simultaneously reduce the coding time, and but also have strong robustness.
