本文采用扩频（SS）技术和自适应DM（抖动调制）技术以及改进的Watson感知模型的数字水印技术应用于立体3D图像的版权保护。改进的Watson感知模型可以很好地解决松弛不随幅度尺度线性变化的问题。实验结果表明，水印方案具有抗高斯噪声、椒盐噪声、JPEG压缩、恒定亮度变化和数值缩放的能力；采用改进的 Watson 感知模型的方案优于使用未改进的 Watson 感知模型的方案。实验中还与文献[4]和[19]进行了对比实验。另一方面，该方法对 JPEG 压缩不敏感，而另一种基于 QIM 的方法对恒定亮度变化和数值缩放不敏感。
In this paper, digital watermarking technique using spread spectrum (SS) technology and adaptive DM (dither modulation) with the improved Watson perception model are applied for copyright protection of anaglyphic 3D images. The improved Watson perception model can well solve the problem that the slack do not change linearly as the amplitude scale. Experimental results show that the watermarking schemes provide resistance to Gaussian noise, salt and pepper noise, JPEG compression, constant luminance change and valumetric scaling; the scheme employing improved Watson perception model is better than the one using unimproved Watson perception model. Compared experiments with the works [4] and [19] were also carried out in experiments. On the other hand, the approach is not sensitive to the JPEG compression while the other based on QIM is not sensitive to constant luminance change and valumetric scaling.
