摘　　要：为了解决纸病检测中多纸病图像分割问题,提出了一种改进的边缘跟踪算法。该算法首先搜索得出纸病边缘的链码,并通过记录坐标取得图像的外接矩形,然后提取每个矩形中的纸病图像。结果表明,该算法能够有效提取纸病图像的边缘,并对多纸病图像能够完成精确的分割。Aiming at the problem of multiple paper defects segmentation in web inspection system, an improved edge tracking algorithm was proposed in this paper. This algorithm firstly tracked the chain code of paper defect edge, and recorded the coordinates to get the bounding rectangle of the image, then extracted defect image of each rectangle. The results showed that the presented algorithm not only could effec- tively extract the edge of paper defect, but also precisely completed the segmentation of multiple paper defects.
