摘要：In the processing of welding X-ray images, the segmentation of welding seams is very important for extracting the welding defects efficiently. A new method based on the horizontal width and the succession of weld seam is proposed, which is used to segment the vertical-type welding seams. The combination of background subtraction and edge detection is used to extract the defects in welding seams. Experiment results show that the proposed method can segment the welding seam efficiently and detect welding defections accurately.
