  contrast masking
A much more precise perceptual model can be achieved by considering contrast masking by determining JND thresholds for each coefficient.
      
Also recent attempts to measure contrast masking by a surround masker found none.
      
Contrast Masking The multiple bandpass mechanisms of the visual system are known to have non-linear response to pattern contrast.
      
Contrast masking is taken directly into account by using the contrast pyramid.
      
Contrast masking refers to the effect of decreasing visibility of one signal in the presence of another signal called masker.

This paper proposes a DWT based blind image adaptive watermarking scheme utilizing HVS and fuzzy clustering theory,through the classification of the image's brightness,texture and contrast sensitivity,people can embed more robust watermark randomly under a certain visual distance,in addition,watermark can be extracted without the access to the original image.In order to improve robustness,we embed the same watermark several times in different positions.Simulation results indicate that the scheme proposed in this paper can survive JPEG compression,noise as well as cropping,so it has the potential practical use.

文章提出了一种基于离散小波变换(DWT)的模糊自适应盲水印算法,根据人类视觉系统的亮度、纹理、以及对比度掩蔽特性,利用模糊聚类来决定水印的嵌入强度,使之可以自适应于图像,水印嵌入位置随机选择,并且水印的检测无需原始图像。为增强水印鲁棒性,笔者在图像的不同位置多次嵌入水印。通过仿真实验,表明算法可以在保证加水印后图像质量的前提下,以最大强度嵌入水印,对JPEG压缩、噪声、图像剪切具有较强的鲁棒性,由于水印检测无需原始图像,该方法具有实用性。

Through the classification of image's brightness,texture and contrast sensitivity,watermark is adaptively embedded in DWT domain.In order to register rotation,scale and translation(RST) transform parameters,support vector machine is utilized to learn image geometric pattern represented by six combined low order image moments.The watermark extraction is carried out after watermarked image has been synchronized without original image.The experiments show that it can embed more robust watermark under certain visual...

提出了一种基于支持向量机(SVM)同步的自适应水印检测方法.该方法利用模糊聚类分析图像纹理、亮度和对比度掩蔽特性,在离散小波变换域自适应嵌入水印信号.为抵抗几何攻击,利用6个图像组合矩表示原始图像的几何特征,通过SVM学习图像旋转、缩放和平移的变换参数,同步后再进行水印的检测和提取.仿真实验表明,该算法在一定的视觉强度下可嵌入鲁棒性更强的水印,能有效抵抗噪声、JPEG压缩和几何攻击,水印检测无需原始图像,具有实用性.
