  本文選題：圖像語義表示 + 語義演化　； 參考：《圖書情報知識》2017年06期

【摘要】：作為記錄信息的一種重要形式,圖像包含了豐富的語義信息。隨著圖像資源的不斷累積,有效的圖像語義表示成為了提高圖像檢索效率的關(guān)鍵。文章梳理了關(guān)于圖像描述與表示的相關(guān)研究,歸納出現(xiàn)有研究仍存在對過程性知識的表示相對不足,反方向的概括關(guān)聯(lián)表示相對薄弱這兩項問題。因此為探究自然有效且可計算的圖像語義表示方式,我們提出以"演化"的視角來剖析圖像的語義表示問題。文章構(gòu)建了基于表示過程的層次描述框架,深入分析了該表示方式的重點與難點,并以具體案例示例說明�；谘莼暯堑膱D像語義表示重視表示結(jié)果與過程,符合用戶解讀習(xí)慣,為更高層次的語義推理和知識發(fā)現(xiàn)累積更豐富且可計算的信息。因此該圖像語義表示方法具有一定的實用性,可被應(yīng)用于輔助專家/用戶的圖像標注等具體實踐領(lǐng)域。
[Abstract]:As an important form of recording information, images contain abundant semantic information. With the continuous accumulation of image resources, effective image semantic representation has become the key to improve the efficiency of image retrieval. This paper combs the related research on image description and representation, and concludes that there are still two problems, that is, the representation of process knowledge is relatively insufficient, and the general association representation in the opposite direction is relatively weak. Therefore, in order to explore the natural and computable image semantic representation, we propose to analyze the image semantic representation from the perspective of "evolution". In this paper, a hierarchical description framework based on representation process is constructed, and the emphases and difficulties of this representation are analyzed in depth, and an example is given to illustrate it. Image semantic representation based on evolutionary perspective attaches importance to the representation of results and processes, conforms to the custom of user interpretation, and accumulates more abundant and computable information for higher level semantic reasoning and knowledge discovery. Therefore, the method of image semantic representation is practical and can be used in practical fields such as auxiliary expert / user image annotation.
