dc.description.abstract | 随着数位化科技以及网路通讯的快速发展,影像资料在医疗院所、数位典藏以及网际网路上被大量的产生,日渐提高了影像检索技术的需求。另一方面由于网路的快速连结,跨越了国界,各种语言的资料都可以在网路上检索。本论文主要研究一个跨语言的医学影像查询系统,让使用者可以使用熟悉的语言或是使用影像内容来找寻相关的医学影像。 本论文探讨的两个研究主题,为医学影像内容查询以及跨语言的资讯检索。在医学影像内容查询方面,我们提出了一些针对学影像内容特征的表示法,相关的相似度计算方法,以及新的接受使用者回馈的模式,在实验结果中显示所提出的特征表示法可以有效的提高准确率及查全率。在跨语言方面我们针对在翻译时所常遇到的岐义性的问题,提出了利用本体知识来改善的方法,实验结果显示我们所提出解决岐义性问题的方法,可以有效提高查询结果的准确率。 | zh_TW |
dc.description.abstract | The importance of digital image retrieval techniques increases in the emerging fields of medical imaging, picture archiving and communication systems. In this dissertation, a bilingual medical image database system is proposed for users to retrieve medical images. The principal objective is to provide users a medical image retrieval system to find similar diagnosis and to obtain useful information for treatment. This dissertation relates to two areas – medical image retrieval and cross-language information retrieval. We proposed an effective representation for content-based medical image retrieval and an approach to address the translation ambiguity problem for cross-language image retrieval. Furthermore, a novel relevance feedback mechanism is proposed to improve the retrieval effectiveness by interacting with users. | en_US |
