| 摘 要： | 由于成像特点及环境干扰，用于工件缺陷检测的红外热像通常较为模糊。为此，将空间域与频域结合的模糊C均值(FCM)聚类算法用于红外热像中缺陷及正常表面的分割。运用多种图像处理方法对原始红外热像进行预处理，将得到的高频图像及其邻域平均图像使用经典FCM聚类算法进行像素灰度的聚类。实验结果表明，该方法的分割效果较好。

| Abstract: | Imaging principle and environment disturbance have lowered the definition of the infrared thermal image.Aiming at this problem,an infrared thermal image processing framework is proposed based on Fuzzy C means(FCM) clustering algorithm with spatial and frequency information.A sequence of preprocessing is applied to the original infrared thermal image.FCM with spatial and frequency information is used on the preprocessed image to segment defect and normal surface of a part.Experimental results show that the proposed infrared thermal image processing framework is very effective to detect the surface defect of a metal part. |
