利用对水印加权的分组技术，盲水印检测器在性能上逼近非盲水印检测器。

Moreover, a classification technique of watermark weights is used, which makes the performance of the detector approximate to that of watermark detectors using original host data.

试验结果表明，该算法能够检测到对水印图像的轻微改动，并且水印检测器对图像的轻微改动输出灵敏度高。

Experimental results show that the algorithm was able to detect slight changes of the watermarking images, and the detector was also sensitive to slight changes.
