Color Image Watermark Based on Run Length Coding and JND Threshold

基于行程编码和JND门限的数字水印算法

Rijndael encryption algorithm is the grouping variable length block cipher.

Rijndael加密算法 是分组长度可变的分组密码.

In Digital Watermarking schemes, JND values can be calculated accurately using visual model, and accordingly embedded location and intensity can be decided appropriately in order to keep balance between imperception and robustness.

在数字水印中利用视觉模型可以比较精确的计算出人眼的JND值，从而确定水印分量的嵌入强度和位置，保持水印的不可见性和鲁棒性间的平衡。

A Multi-Resolution Algorithm of Watermarking Based on JND Threshold

基于人眼JND门限的多分辨率水印嵌入算法

This algorithm utilizes JND threshold model of DWT domain to embed watermark values, able to primely distinguish common image processing from vicious tamper and be sensitive to vicious tamper and effectively orient the region of tamper.

该算法能够很好的把一般图像信号处理与恶意篡改攻击区分开来，并且对恶意篡改是敏感的，能够很好的定位篡改区域。

The paper also describes the pivotal technologies which are applied in the software implementation and gives the experimental result and evaluation. The paper lastly provides a new evaluating indicator which uses JND to evaluate information carrying.

文章还对软件实现采用的关键技术进行了阐述，并给出了测试结果与评价，最后还提出了一种新的信息搭载评价方法-用JND值评价信息搭载。

In contrast to conventional JND ( Just Noticeable Difference) threshold model, JPW describing minimum perceptual sensitivity weighting to noise changes, is fitter for nonadditive watermarking.

与传统的仅可见视差（JND）阈值模型相比，JPW刻画了对噪声变化的最小感知权重，它更适合于非添加型水印。

In this experiment, the control effects of antagonistic bacterium ( B-916, H-91, G-329, P-6854 and JND) a-gainst some common diseases in solanaceous vegetables ( root rot, damping-off and early blight of tomato) were studied.
