dc.description.abstract | 隨著數位化科技以及網路通訊的快速發展,影像資料在醫療院所、數位典藏以及網際網路上被大量的產生,日漸提高了影像檢索技術的需求。另一方面由於網路的快速連結,跨越了國界,各種語言的資料都可以在網路上檢索。本論文主要研究一個跨語言的醫學影像查詢系統,讓使用者可以使用熟悉的語言或是使用影像內容來找尋相關的醫學影像。 本論文探討的兩個研究主題,為醫學影像內容查詢以及跨語言的資訊檢索。在醫學影像內容查詢方面,我們提出了一些針對學影像內容特徵的表示法,相關的相似度計算方法,以及新的接受使用者回饋的模式,在實驗結果中顯示所提出的特徵表示法可以有效的提高準確率及查全率。在跨語言方面我們針對在翻譯時所常遇到的岐義性的問題,提出了利用本體知識來改善的方法,實驗結果顯示我們所提出解決岐義性問題的方法,可以有效提高查詢結果的準確率。 | 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 |
