摘要
随着数字水印技术的快速发展，数字水印系统性能评估越来越显重要。指出了水印性能评估研究的重要性，在论述数字图像水印不可感知性、鲁棒性、水印容量等几项性能评估指标的基础上，提出了水印性能评估的一般步骤，以及主客观评估标准，最后对未来数字水印性能评估进行展望。研究表明，建立公平统一的数字水印系统性能测试与评价体系对于数字水印系统性能的提高和系统的完善是至关重要的。
The rapid development of digital watermarking technology has made performance evaluation of digital watermarking more and more important. It is pointed out that establishing performance evaluation of digital watermarking is important. Based on the description of the major performance indices of imperceptibility, robustness and watermark capacity for digital image watermark, general steps for performance evaluation and both subjective and objective evaluation standards are proposed. Finally, the prospects for performance evaluation of future digital watermarking are given. It is crucial to establish impartial uniform performance-testing and evaluating system for improving the performance of digital watermarking.
