應用模糊邏輯的攝影構圖辨認方法 / A Fuzzy Logic Approach for Recognition of Photographic Compositions

黃瑞華, Huang, Jui Hua Unknown Date (has links)
本論文應用攝影構圖法則,以模糊邏輯理論為基礎,判別影像的攝影構圖類型。構圖(Composition)乃是攝影這項平面藝術創作最重要的美學元素之一,其目的是利用空間中的物體配置,經由透視投影後,讓畫面的整體呈現平衡感;專業的、優秀的攝影作品,皆會符合攝影的基本構圖原理。因此許多的影像增強、影像合成的應用中,也應該配合相片原本的構圖設計,針對所欲表達的重點予與適當地調整,而非「盲目的」以一體適用的法則去處理每一張照片。 論文中,我們針對影像所欲表達的重點區域,分析其結構特性,設計不同的特徵,並以模糊邏輯理論為基礎,應用Mamdani系統,結合隸屬函數與攝影構圖判別法則的交互作用,用以辨認所欲處理相片的構圖類別。依據辨認後的構圖類別,即可對該影像做適當地分割及調整,以使相片能有最佳的影像增強處理。 實驗證明,本文所提出的方法能有效地辨認攝影構圖類別,針對不同攝影構圖所作的影像修正,才能更符合人眼的視覺喜好。 / This thesis addresses the problem of how to recognize the photographic composition from a given photo based on the theory of fuzzy logic. Composition is one of the important aesthetics for the plane figure photo art. To present the balance of its holistic picture, it takes the advantage of special object arrangement after acting perspective projection. A piece of professional and qualified photo work will realize these basic photo composition methods. For many applications about the digital photo, the operations, i.e., photo enhancement, segmentation, output, and synthesis, all need to match up the photographic composition to do accurate processing rather than “blind” processing that assumes each photo with the same “composition.” An automatic recognition method using image features from some specific regions is described. The method is employed in a Mamdani model and combines outputs of multiple fuzzy logic rules and feature extraction algorithms to obtain confidences that can identify the correct photographic composition. Experimental results show that the proposed method is robust and effective for photographic composition recognition. The feature with adjusting in different photo composing will be able to comfort our human sight.

模糊卡方適合度檢定 / Fuzzy Chi-square Test Statistic for goodness-of-fit

林佩君, Lin,Pei Chun Unknown Date (has links)
在資料分析上,調查者通常需要決定,不同的樣本是否可被視為來自相同的母體。一般最常使用的統計量為Pearson’s 統計量。然而,傳統的統計方法皆是利用二元邏輯觀念來呈現。如果我們想要用模糊邏輯的概念來做樣本調查,此時,使用傳統 檢定來分析這些模糊樣本資料是否仍然適當?透過這樣的觀念,我們使用傳統統計方法,找出一個能處理這些模糊樣本資料的公式,稱之為模糊 。結果顯示,此公式可用來檢定,模糊樣本資料在不同母體下機率的一致性。 / In the analysis of research data, the investigator often needs to decide whether several independent samples may be regarded as having come from the same population. The most commonly used statistic is Pearson’s statistic. However, traditional statistics reflect the result from a two-valued logic concept. If we want to survey sampling with fuzzy logic concept, is it still appropriate to use the traditional -test for analysing those fuzzy sample data? Through this concept, we try to use a traditional statistic method to find out a formula, called fuzzy , that enables us to deal with those fuzzy sample data. The result shows that we can use the formula to test hypotheses about probabilities of various outcomes in fuzzy sample data.
