    Abstract: 隨著電腦發展及科技進步,文字、圖像、語音等非結構化資料的儲存及分析日漸活躍,大數據分析愈來愈普遍應用於生活之中,讓我們能夠體驗數位化時代的方便。以圖像資料為例,車牌辨識、人臉辨識等人工智慧的大量運用,不但讓身份確認更有效率,也減少人力成本及提高辨識準確性,可預期處理圖像資料的需求將更為多元。本文也以圖像辨識為研究目標,探討如何結構化圖像資料,找出較為合適的變數產生方式,作為圖像分類的判斷依據。除了提出圖像資料結構化的方法,本文也考量常見分析圖像的變數,包括:顏色、色調等定義方式,將上述變數代入分類模型,再與統計、機器學習模型比較,找出最佳圖像資料的分析組合。
    除了使用常見的三原色、冷暖色、邊緣、紋理、位置等方法將圖像資料結構化,本文提出將圖像以等分切割(Splitting)成k×k塊,並以百分位數的方式篩選上述結構化資料的主要特徵,代入執行速度相對較快的統計模型(如邏輯斯迴歸),並與機器學習模型比較分類成效。本文考量五種圖像資料,包含臺灣報紙頭版、美國Vogue雜誌封面、台灣Vogue雜誌封面、十九世紀油畫資料(寫實派、印象派)、超寫實油畫,透過交叉驗證比較各種圖像變數定義、分類模型以及維度縮減結果。此外,本文提出的切割法也具有詮釋的功能,可找出區隔圖像風格的重要特徵,也能作為維度縮減的替代方法。研究結果顯示:圖像的等分切割法之分類結果最佳,準確性略高於類神經網路,兩者都明顯優於三原色等常見方法;另外,等分切割法僅需使用大約40%原始資料的變數即可達到原始資料97%變數的效果。
