Abstract:Through analyzing the present state of welding flaw X-ray test method and open question, in view of the fuzziness of flaw image and the requirement in practical application, a watershed segmentation method was proposed based on the dynamic combination rule. An improved method was based on the watershed algorithm, which had effectively restrained the over-segmentation occurrence by means of presented combination whilst segmentation in accordance with the dynamics combination rule. Experimental results show that the algorithm can quickly and accurately obtain the segmentation result of flaw image obtained from industrial ray. Furthermore, it has higher ability in resisting noise.
Keywords:watershed  over-segmentation  dynamics combination rule  flaw image
