| 中文摘要: |
| 提出了一种基于段的连通域标记处理算法，同时对纸病区域进行连通域标记和形状特征值提取，旨在提高纸病检测的准确率和效率。该算法利用纸病区域为简单连通图像的特点，采用段技术实现了纸病区域的标记处理，探讨了在标记处理同时快速统计与形状特征值计算有关的中间参数的方法，利用标记结果及形状特征值实现了纸病的快速检测。该算法优化了标记处理与形状特征值提取的过程，减少了纸病图像的扫描次数。结果表明，该算法达到了准确、快速的纸病检测效果，且易于扩展到实际的纸病检测系统中。 |
| Abstract: |
| In order to enhance the accuracy and efficiency of paper defect detection， this paper presented a run-based connected-component labeling algorithm， which could obtain the features of paper defect regions during the connected component was labeled. According to the regions of paper defects are simple connected image， we used a run-based connected-component labeling to record the intermediate results related to the image shape feature extraction during the labeling processing， and combined the labeled results and shape feature values to realize the paper defect detection rapidly. This algorithm could reduce the times of scanning images because it optimized the process of connected-component labeling and shape feature extraction. The experimental results demonstrated that the proposed algorithm could achieve an accurate and efficient detection result for general paper defects， and easily be used in the actual paper defect detection system． |
