研究了小波技術在圖像邊緣提取中的應用，解決了目前圖象中存在的局部分割問題，提出了鏈的百分比概念；針對分割結果的不封閉性，采用邊緣點生長的方法，有效地解決了區域的封閉性。最后通過尋找大區域解決了高細節區的分割問題。
關鍵詞：高斯濾波；小波；邊緣點；大區域

Indrawing on the picture edge base on the wave technology Luo Yun,Chen Liwei
(College of Computer Science & Technology, Southwest University of Science and Technolog, Mianyang 621010) Abstract：Have studied the wave technology’s application in drawing on the picture edge , the local segmentation problem preliminarily solved existing in the picture. The traditional chain-length concept is discarded and the percentage concept of the chain is proposed. The edge-growth method is adopted to get the good closed image. Lastly the image segmentation is implemented by finding large regions.
Key words：gaosi_ filter; wavelet; edge-growth;large regions
