| 摘 要： | 充分利用车牌字符的局部与整体特征，提出了字符串的车牌相似度概念．并在此基础上提出了一种新的车牌字符切分算法．该算法将搜索连通区域切分与投影切分结合起来，通过聚类分析，遍历各种切分的可能情况，最终按照车牌相似度最大的字符串完成字符切分．实验结果表明，该算法有很好的可行性和有效性．

| Abstract: | The local and global characteristic of characters of the license plate is fully used and the concept of the similarity between a character string and the license plate is introduced, on the basis of which a new algorithm for the character segmentation of the license plate is proposed. Using connected-component searching and projection, this algorithm enumerates all the possible segmentations. And then it analyses the segmented characters using clustering. Finally, it selects a character string that has the maximal similarity to the license plate to segment the character. Experimental results show that the algorithm has good feasibility and effectiveness. |
