查询词典 sensitivity threshold

This paper brings forward a approach for textile flaw automatic detection based on optimal Gabor filters. At first the niche genetic algorithm is employed to attain the parameters of the optimal Gabor filters and segmentation threshold based on the feature of the unflawed textile,and then apply the optimal Gabor filter and threshold on the fabric image to achieve the resnlts.

为了对织物缺陷进行快速准确的自动检测，建立了一种基于Gabor滤波器的织物缺陷自动检测方法，即首先根据无缺陷织物的结构特征，应用小生境遗传算法寻找最优的Gabor滤波器参数和分割阈值；然后将待检图像通过滤波和分割来得到检测结果，同时根据响应矩阵的极小值点来计算缺陷的形状特征。

A series of experiments were done to substantiate the feasibility of the different piezoelectric cochlea implants in vitro and in vivo . The unpoled ceramic had no piezoelectric characteristic and no ability to decrease the threshold, while the poled ceramic had obvious piezoelectric effect to recover the hearing. Based on these results, it can be affirmed that the piezoelectric cochlea implant can activate the nerve and decrease the threshold.

本研究通过未极化与极化的高灵敏性压电陶瓷的对比，从体外模拟实验中的声电响应曲线和动物体内植入实验的结果中得到：未极化的压电陶瓷没有压电响应，而极化后的压电陶瓷能够将声音信号转化为电信号，证实了压电陶瓷的压电特性的确可以刺激动物的听神经，从而降低听阈阈值。

实验结果表明：阀值电压不仅与螺距数有关，而且与边界条件引起的螺距收缩和伸展有关，在螺距数不变的情况下，螺距的收缩使阀值电压提高，而螺距的伸展使阀值电压减小。

Firstly, there are less secure and efficient threshold schemes; secondly, the research on multi-secret sharing is rather weak; thirdly, usual verifiable secret sharing don't consider the partners' anonymity, while it is just people's expectation. Last but not least, the problem of variety on shares is becoming a more obvious restrict of efficiency, especially in the facets of the lost and being districted of shares. On the application of verifiable secret sharing, there are also two inadequates : on the one hand , verifiable secret sharing has been used in much threshold cryptography but in less verifiable signatures.

然而，经过认真总结、分析该领域目前研究的发展状况（具体结果将在第一章给出），我们发现在可验证秘密分享的研究方面，仍有下列四个不足之处：一是现有的安全、高效的门限方案不多；二是对多秘密分享的研究非常薄弱，在已有的文献中还见不到安全、实用的可验证多秘密分享方案；三是通常的秘密分享方案没有考虑秘密分享者的匿名性，而这恰恰是人们所希望的；四是秘密分享者的动态管理问题已经越来越明显的制约现有方案的安全，尤其是密钥份额丢失或被破坏时如何恢复更是没有被深入探讨。

通过单阈值IK法与普通克立格法、反距离加权平均法的估计效果比较，发现单阈值IK法可用于具有一定风险条件下的区域性土壤水盐空间插值，该法无需处理特异值，可直接进行估计，估值效果明显优于传统反距离加权平均法，对OK法的平滑效应也有一定改进。

We also study on the coding performance of these wavelet. At last, we investigate the wavelet threshold denosing for image, and present a improved Bayes denosing for image. We also combine the wavelet image coding with image denosing based on wavelet threshold, the noising image is compressed, the noise is de-noised at the same time.
