摘要:
为了提高图像版权保护与信息跟踪的可靠性,提出了一种基于最小二乘支持向量机的纹理掩蔽特性数字水印技术. 图像区域子块的纹理越复杂,人眼可感知的视觉门限就越高;对于边缘区域,该视觉门限最高,在特征区域中可以选择这些位置作为水印的嵌入点. 根据图像子块邻域像素间的相关性原理,使用最小二乘支持向量机建立起邻域像素之间的关系模型,动态地调整模型的输出值同中心像素值的大小关系,实现水印信息的嵌入与提取. 同时,用粒子群算法来优化水印信息的嵌入强度. 实验表明,嵌入水印后的图像不仅有着很好的隐蔽性和较强的稳健性,对联合图像专家小组压缩、几何剪切、放缩等一般的图像处理操作,有着较强的抵抗力,同时实时性、安全性都比较强.
Abstract:
To improve the reliability of copyright-protecting and information-tracking, a digital watermarking algorithm of the texture masking characteristics was proposed by the least squares support vector machine (LS-SVM). As the texture of the region sub-images becomes more complex, the just noticeable difference (JND) of the visual perception is higher, and the JND is the highest at the edge regions where the watermark is embedded. According to the correlation theory of the sub-images neighboring pixels, the relationship model of sub-images neighboring pixels was established by the LS-SVM. The watermark was embedded and extracted by dynamically adjusting the interval of the center pixel and the output of the model. Meanwhile, the particle swarm optimization was used to seek optimal embedding strength of the watermark. Experimental results show that the images embedded into watermark have good masking quality and high robustness, and can resist the common image processing operations such as the joint photographic experts group compression, the geometric cropping, the rescaling and so on. The images also possess good practicability and security.
