| 摘 要： | 分析示温漆（TIP）图像特征，根据等温线附近产生局部梯度极值的特点，实验对比了4种边缘提取算法效果。根据实验结果，选用Canny算子提取等温线。提出在边缘提取前进行K means聚类处理，并对K means聚类算法和Canny算子进行了改进。提出了两种K means初始聚类中心的选择方法，更适于示温漆图像的分割。改进了Canny算子的内核，提升了等温线的质量。结果表明:该算法能够快速提取清晰、连续的等温线，效果良好，满足工程应用要求，已用于示温漆自动判读软件开发。

| Abstract: | The feature of isotherm in temperature indicating paints (TIP) images was analyzed, four kinds of edge extraction algorithms were experimented and compared, extracting isotherms with Canny edge extraction was suggested and the K means clustering algorithm was used before the edge extraction. The K means clustering and Canny edge extraction were improved. Two methods of choosing the K means initial centers were proposed, which were more suitable for TIP image segmentation. The Canny algorithm to detect isotherms with higher quality was improved. The algorithm could extract clear and continuous isotherms fast. Experimental results show that the algorithm proposed runs well, and satisfies the engineering application needs. Now it has been well applied in TIP automatic temperature interpretation software development. |
