獸面紋又稱做饕餮紋，其盛行於商代至西周早期，但早在夏代青銅器上就已發現這種紋飾，饕餮是古人想像出來的怪獸，進而再融合自然界中各種猛獸的特徵而成。一般形象是以鼻樑為中線，兩側成對稱排列，有大眼和頭上兩個大角，以及一個沒有下唇的大嘴。非相片寫實電腦繪圖技術(Non-photorealistic Rendering)不同於傳統的電腦圖學技術，著重於產生各式各樣不同於光學物理的繪圖效果。最重要的是如何分析各種藝術的結構和技巧，進而加以統整之後，建立系統性的演算法，將其重現於數位空間。本論文便是針對中國古代所流傳下來的獸面紋圖樣的設計創作去做分析，從而發展出一套系統，讓使用者輸入一張任意的動物圖像，將此圖像標示出特徵部位後再與我們收集的獸面紋樣資料庫做簡單的比對和變更，自動的產生繪製出具有中國古代獸面紋圖樣特徵的結果。 / Animal-mask decoration, also known as the taotie pattern, is an art stylization commonly found on bronze vessels from the Shang Dynasty to the early Western Zhou Dynasty. Taotie is an imagined gluttonous monster, which is composited with the characteristics of various wild animals. The general layout of taotie is a symmetrical face with pair of large eyes and horns, and a big mouth without lower lip. Non-photorealistic computer graphics (NPR) technology tries to produce all kinds of effects different from the optical physics, and focuses on analyzing and integrating the principle of the various arts and skills to establish a systematic method to reproduce the stylization. This thesis tries to analyze the structure of the traditional animal-mask decoration, and building a system to transfer the stylization. The User can input an animal photograph and manually select few feature points. Then the proposed algorithm will automatically extract the feature and find the correspondence in the example Database to create the new animal-mask decoration with the feature in the input photograph.
