摘  要:该文以在StirMark中对含水印图像实施JPEG压缩攻击为例,探讨StirMark在水印方案鲁棒性分析中应用。为了验证StirMark的性能,该文以基于DwT-SVD的图像盲水印算法作为实例,对给定的水印图像通过StirMark生成各种攻击修改图像,最后以JPEG压缩攻击为例,详细地分析了利用StirMark批量生成不同质量因子压缩下的修改图像,在水印检测时,相互关联的文件名为我们一次性执行水印提取和检测水印DCT相关系数奠定了基础,与通过代码生成批量攻击文件相比,StirMark基准测试程序具有较高的效能,同时从日志文件获得水印算法执行时间和鲁棒性量化值,对评测水印算法的性能,改进水印算法提供了有力的依据。This paper discusses the application of stirMark in the analysis of robust watermark, for example, JPEG compression at- tack in the StirMark implementation of the watermarked image. In order to verify the performance of StirMark, for example, In or- der to verify the performance of StirMark, in this paper the image blind watermarking algorithm based on DWT-SVD as an exam- ple, StirMark generates a variety of attacks that modify the image for the watermark image given, lastly, JPEG compression attack, for example, analyzes in detail the modification image of Compression of different quality factor using StirMark, When we detect watermark, Interrelated documents lay a foundation called our one-time implementation of watermark extraction and detection of the watermark in the DCT correlation coefficient, Compared with the handwritten code StirMark is efficiency, at the same time ob- tains the watermarking algorithm execution time and the robustness of the quantitative value from the log file, fully Contribute to the performance evaluation of watermarking algorithm, further improves watermarking algorithm, the robustness and security of watermarking algorithm has better.
