The methods of adaptive median filter, variance ratio of interclass and intraclass segmentation, and mathematical morphology were used to decrease the noise of original welded seam image, to extract welded seam region, and to carry on high frequency enhancement transformation for the interior of extracted welded seam with frequency range sharpening.

利用自适应中值滤波方法和类间、类内方差比分割法及数学形态学方法对原始焊缝图像进行降噪和提取焊缝区域，并对提取的焊缝内部进行频域锐化的高频加强变换。

Simulation results indicated that the adaptive median filtering effectively removes noise, and maintain the details of welded seam and defection edge; the variance ratio of interclass and intraclass segmentation could accurately distinguished between the welded seam metal and the base metal together with mathematical morphology method; high frequency enhancement extrudes the welded seam center, consequently defects would be detected.

仿真结果表明自适应中值滤波能够有效去除噪声，并保持焊缝和缺陷的边缘细节；类间、类内方差比分割方法与数学形态学方法并用，能准确的将图像分割为焊缝与母材区域；高频加强变换能够使焊缝中心部位突显出来，从而实现缺陷的检测。
