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．
