This algorithm uses HSV colour space which is more compatible with human's visual sense feature and takes advantage of human's perception feature on colour to quantise colour components in non equal interval and to form the eigenvector. Then it uses histogram intersection distance algorithm to match pieces' feature, and according to the characteristic of stitching pieces of image its own, the image segmentation technique is adopted to cull the background of the piece, and simultaneously the approach to match the pieces by direction is implemented.

算法采用符合人类视觉特性的HSV颜色空间，利用人对颜色的感知特性对颜色分量进行非等间隔的量化并形成特征矢量，应用直方图相交距离进行了特征的匹配，并且针对拼块图像自身的特点采用了图像分割技术对拼块图像的背景进行剔除的同时实现了按方向进行匹配的方法。

The first feature of the model is the essence of each helix transformation; the second feature of this model is the inter-impact among these triple helixes; the third feature is the triple network and the re-superposition generated from the interaction among these triple dimensions.

为此，本论文得出以下几个方面的结论：(1)政府、产业和大学&三重螺旋&是一个创新模式，这一模式抓住了在知识资本化进程中，不同阶段制度安排的多元互惠关系。

Aiming at the leakage for the security of PCA, a secure face recognition algorithm was proposed, based on adaptive non-funiform quantization which quantizes the template feature obtained by PCA and stores the hash value of the quantization feature instead of the template feature.

分析了主成份分析方法的安全性，针对其存在的安全漏洞，提出了一种基于自适应非均匀量化的安全人脸识别算法，将主成份分析方法得到的人脸模板特征进行量化，用量化特征的哈希值代替人脸模板特征存储在数据库中，并给出了该算法的安全性分析。

Defines a conditional default value for a feature; the condition is specified as a feature structure, and is met if it subsumes the feature structure in the text for which a default value is sought.

定义一个功能的条件预设值；该条件被指明为一个功能结构，且若在需要预设值的文本中包含该功能结构时，则表示条件符合。

This dissertation brings forward and realizes one method of establishment of handwritten Chinese character library on account of feature of characters' shape: first, scan the characters wrote on paper to the image file, then break up the whole piece of characters image to solo character, and do some feature extraction. After this, pick up the feature of the image and write in file supervened.

本文提出并实现了基于字形特征的手写体汉字字库的构建方法：先将在纸上书写出的字符扫描成图像文件，然后对整幅的字符图像进行分割，将其分割成一个个的字符，再对图像进行一系列的预处理，接着抽取图像特征，写入文件。

Aiming at feature point based image registration, we suggest the concepts of broad sense feature point and narrow sense feature point.

针对基于特征点的图像配准，本文提出了一种基于广义特征点的图像自动配准方法。

For enhancing the system performance, the simple bit-wise indexing method was applied to the manufacturing defect detection problem, time aspect for manufacturing domains. For improving the flexibility and accuracy, the encapsulated bit-wise indexing method is applied to the pattern matching module of an Internet intrusion detection system. To reduce the processing time, the compacted bit-wise indexing method is applied to the data-driven rough-set based feature selection. Additionally, the proposed feature selection method was adopted in a KA project to discover the desired feature sets to construct a CBR system for a world-wide financial group customer relationship management system's loan promotion function.

The results showed that the peak latency and pattern of SEPs elicited by electrical needling in LI-l1 and MP were similar. The amplitude of SEPs elicited by electrical needling in LI-l1 was higher than that of MP. There was no obvious SEPs generation when MM was electrical needling.

结果显示，电针刺激曲池穴和其邻近桡侧伸腕长肌运动点诱发性脑电波的波形和波峰时间是类似的，只是穴位的诱发性脑电波波幅较大，而电针刺激非穴位点并没有明显的诱发性脑电位。
