針對制鞋業中鞋樣的錄入問題，提出了一種實現從圖像格式到圖形格式轉化的圖像
矢量化方法。并且形成的圖形文件可根據不同鞋業CAD 軟件的要求而存儲成相應的格式。該方法還在輪廓跟蹤過程中采用了各種優化算法，從而節省了搜索時間，提高了輪廓線擬合精度，符合了鞋子設計的特殊要求，為鞋業CAD 軟件的應用提供了良好的基礎。

Abstract: According to shoe sample input in shoes manufacturing, a new method for image
vectorization which can convert image format to graphics format is presented. And the special
graphics file will be created according to the different shoes manufacturing CAD software. And in the course of contour tracking all kinds of optimization methods are adopted. It saves time searched，improves contour curve fitting, satisfies special requirements of shoes design and supports a good basis of application on shoes manufacturing CAD software．
Keywords: shoe sample, vectorization, direction module, contour tracking
