查询词典 data point

Xie-Beni index decreases with the number of partitions increasing. It is difficult to choose the optimal partition of data when the number of clusters is large. From the point of view of the compactness and the separation of clustering, a novel clustering validity function is proposed, which is based on the improved Huber Г statistic combined with the separation of clustering.

针对此问题，分别考察改进的Hubert Г统计量和聚类分离度，导出一个新的基于数据几何结构的聚类有效性函数，使得它有惟一的最大值，函数值随聚类个数增大而递减的趋势并不影响最优聚类个数的判定。

The computation results on real seismic data show that mutual information in the sliding observation window can indicate the existence of the seismic signals to be detected. Through the pickup of the rising-break or the peak point of mutual information, the arrival time can also be effectively estimated.

计算结果表明，互信息量随滑动窗口移动的变化情况可以明确标示出待测地震信号的存在，通过提取互信息量的突变点或峰值点，能够有效拾取地震波的初至时刻。

You can get the BLOB field data instead of opening file. The point is you need to return a Byte Array.

你能获得一个BLOB字段来代替打开的文件，关键是你要返回一个字节数组。

This article studies the effect of applying the policy using these years' data of a basic people's procuratorate organ, and point out some problems and gives several reasonable advices.

本文通过对近年来基层检察院适用该政策的数据分析，说明该政策适用的实际效果，并提出该政策实施中存在的问题和合理建议。

Compared with the prior art, the invention has the advantages that the method first identifies the expression of a facial image in video image data, and then drives the organ in a corresponding three-dimensional facial model according to the preset organ driving rule, thereby achieving more vivid animation effect; and the method avoids animation effect deviation caused by the movement detection errors of a single organ characteristic point when the prior art adopts single organ driving.

与现有技术相比，本发明的优点在于：本发明先识别视频图像数据中人脸图像的表情，然后依据预设的器官驱动规则，再来驱动相应的三维人脸模型中的器官，可以达到更加逼真的动画效果；避免现有技术采用单个器官驱动时，由于单个器官特征点的运动检测误差而导致的动画效果偏差。
