Application of an improved watershed algorithm in welding image segmentation

Wang M. , Wang Yu. , Chai Li.


In view of the present state of welding flaw X-ray test method and open question, a watershed segmentation method is proposed based on the dynamic combination rule. In consideration of image structure information, this paper presents an improved method based on the watershed algorithm, which has effectively restrained the over-segmentation occurrence by means of combination whilst segmentation in accordance with the dynamics combination rules. Experimental results show that the algorithm can quickly and accurately obtain the segmentation result of flaw image. Furthermore, it has higher ability in resisting noise.
