| 摘 要： | 针对传统图像马赛克算法中的瓦片图像颜色调整问题，提出一种基于全局色彩传递的图像马赛克算法，提高瓦片图像对源图像颜色空间的拟合阶数，在此基础上采用矩形碎片图像拼贴方式实现了相应的马赛克系统。实验结果表明，该算法能够获得良好的性能。

| Abstract: | Since the keyword-based search engine can not meet the needs of users and the traditional way of query expansion brings out the errors of semantic understanding, this paper proposes an ontology-based conceptual model of vertical search engines, and sets up a two-tier index structure based on keywords and concept. Taking advantage of industry domain ontology, it operates semantic query expansion to the key words which is submitted by the user, and optimizes the sorting of documents marked by ontology, then raises rate of precision and recall of the system. |
