A: This welded seam is found an obvious air hole and an unqualified undercut with macroscopic check.

這個焊口以宏觀檢查發(fā)現(xiàn)明顯的氣孔和超長的咬邊欧美一级作爱牲交片免费观看。

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.

利用自適應中值濾波方法和類間、類內(nèi)方差比分割法及數(shù)學形態(tài)學方法對原始焊縫圖像進行降噪和提取焊縫區(qū)域，并對提取的焊縫內(nèi)部進行頻域銳化的高頻加強變換。

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.
