| 中文摘要 | 通过分析焊接缺陷X射线检测方法的现状和目前存在的主要问题,针对缺陷图像的模糊特点和实际应用的要求,提出了一种基于动态合并准则的分水岭分割方法。阐述了在分水岭算法的基础上做的一些改进,其内容是通过动态合并准则进行边分割边合并的方法,有效地抑制了过分割现象。结果表明,该方法对工业射线获取的缺陷图像能够快速、准确地得到分割结果,并且具有较强的抗噪声能力。; 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.; 中国博士后科学基金资助项目(2005038095); 山西省自然科学基金资助项目(20051043) |
