local similarity

Considering the special structure of question database, a vector space search model based on text segment is adopted. An improvement on the traditional TF-IDF formula is made, and local similarity and global similarity are combined to sort the search results.

针对题库结构的特殊性，采用了基于文本段的向量空间搜索模型，对传统的TF-IDF公式做了改进，并使用局部相似度和全局相似度相结合的方法实现搜索结果的排序。

However, due to the image noise, feature extraction algorithm, as well as local similarity of non-stereo matching points, there must be some false matching between the images.

然而，由于图像噪声、特征点提取算法以及非匹配点的局部相似性和遮挡的影响，相关匹配中必然存在较多的误匹配。
