查询词典 segmentation-cavity

This system includes two steps of segmentation and recognition. In the second step, first, a segmentation method is adopted to find the character nonlinear segmentation paths by combining gray scale and binary information based on a Viterbi algorithm; then, a recognition method of using a Viterbi algorithm is adopted to dynamically combine and recognize the character candidates with their reliabilities generated from the recognizer.

Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.

第二种方法，基于双向角度微分的边点提取法，针对三维正交模型采用基于截面线的方式组织数据，此方法比基于曲率半径方法更简洁，不用进行曲面拟合，大大提高了计算速度；计算过程中由数据点的直接差分逼近微分，但直接差分对数据误差敏感，为此，本文提出了阈值过滤的方法，一方面过滤了数据误差在计算结果中引起的噪音，另一方面可以按照设计意图控制边点的提取；来决定是否提取光滑交接的边点。

Customer segmentation is a critical step to the success of target or segment marketing. The effectiveness of customer segmentation depends on a good number of variables such as customers' demographic, behavioral, geographic, and psychographic characteristics. However, the huge combinations and correlations among variables make customer segmentation a challenging task, even with the aids of information technologies. The industry is desperate for effectual and powerful tool for excavating customer knowledge from the large accumulated data in the corporate database management system.
