摘要

刺繡是中國優秀的傳統手工藝之一，至今至少有两、三千年歷史。這是一種用針和線在織物上縫製出各種精美圖案的藝術。時至今日，刺繡還是非常流行，特別是在生活和藝術裝飾方面。但是這種藝術形式在計算機圖學領域的研究非常少。本篇論文提出了一種方法用電腦合成刺繡作品。我們首先從圖片中獲取物體的資訊，接著建立三維繡線模型，然後設計了三種常用的刺繡針法，對不同的區域使用不同的針法，最後根據繡線的光學性質，用基於物理的渲染方法繪製出圖片。所得結果跟真實的刺繡非常相似。

Chinese embroidery is a traditional handicraft, which has a long history. By using a needle, thread or yarn is sewn on to a base material or fabric to create a pattern. Today, embroidery continues to be a popular handicraft especially in life and artistic decoration. But this art form has not drawn enough attention in computer graphics field. In this thesis, we propose a method to synthesize embroidery. We first extract the region we want to embroider by image processing technology. Then, we build a 3D stitch model. Next, we design three stitching styles and put the stitches in the regions. Finally, we render the result by physically-based rendering technology. The results have realistic visual effect.
