摘要
在简要分析基于单一幅值位平面嵌入BPOF水印的基础上,讨论了使用多个幅值位平面嵌入水印并进行了性能分析。通过仿真实验得到了优化方案:以多个幅值位平面嵌入水印,而从其中的最高位平面中提取水印可以明显提高水印性能。
Based on the brief analysis of embedding the BPOF( binary phase-only filter) watermark into single bit plane, the watermark embedding with multiple bit planes and analyzed its performances was discussed. The optimized scheme is obtained via simulation experiments: embedding the watermark into multiple magnitude bit planes, while extracting the watermark from the highest one of them, will improve the watermark performance markedly.
