研究了小波技术在图像边缘提取中的应用，解决了目前图象中存在的局部分割问题，提出了链的百分比概念；针对分割结果的不封闭性，采用边缘点生长的方法，有效地解决了区域的封闭性。最后通过寻找大区域解决了高细节区的分割问题。
关键词：高斯滤波；小波；边缘点；大区域
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
