jnd的音标

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.

利用拮抗细菌（B-9l6、H-91、G-329、P-6854和JND）对茄果类蔬菜几种常见病害（根腐病、猝倒病和早疫病）进行室内外生物防治试验。

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。

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。
