環狀編織圖騰是編織手工藝的一種面貌,最大的特徵是他環狀對稱的特性。時常可見於我們的日常生活中,包括了傢俱裝飾、杯墊等等。這樣的手工藝編織品其中最困難的一環便是設計,如何設計出新穎不落窠臼且美觀的樣式需要大量的經驗以及技術。對於新手來說,往往不是件容易的事。
在此篇論文中,我們提出了一針對環狀編織圖騰的混和生成系統。透過混和真實的編織圖騰,產生全新的樣貌。然而在自動產生的過程中,他仍需保留環狀編織圖騰的性質,而不是變成個四不像。我們採用了圖像變換之方法,利用其本質上繼承樣本之特性,將他們也表現在新產生的圖騰之中。針對這個方法,我們亦提出一可參數化之樣本相似度權重,用以控制生成時的質和量,以確保生成圖騰的特性。論文的最後,我們也以不同的環狀編織圖騰來驗證此篇論文的成效。希望盡綿薄之力,幫助那些我們可能有能力幫助的人。

Tattings belong to the family of decorative handicraft of lace. The tatting patterns are radial symmetrical, well structured and strictly connected. As one of the most prevailing textile art, the design of tatting pattern is always in demand. However, designing neoteric patterns requires considerable of experience and skill, which serves as barriers and discourages the beginners.
In the thesis, we present a new hybridization framework dedicated for tatting patterns. The proposed framework generates new patterns by means of hybridizing real-world tatting exemplars. We consider the hybridization as a spatial metamorphosis problem. The hybrids thus inherits the characteristics of exemplars by the nature of metamorphosis, making it similar but different. The metamorphosis is achieved by an optimization of bidirectional similarity of hybrid with each exemplars. Besides, a parametrically controllable source-similarity weight is proposed to govern the hybridized appearance and ensure the fundamental tatting properties. The proposed method has been examined through applying to a wide variety of tatting patterns.
We hope our framework and the patterns generated could be a help for those in need.
