摘要
利用复合算子和方向曲线的方法建立了一种基于方向曲线的焊缝Ｘ光片中夹渣类缺陷的自动识别算法。该算法计算量小、判决速度快、实时处理效果好、识别率高，并且具有良好的适应性。试验结果表明这是一种良好的特征识别方法。
A new recognition algorithm using composite operator and direction curves to auto detect the dreg defects in X rays photo is proposed in this paper. This algorithm is simple with little computation, fast detection speed, good effect of real time process, high accuracy of detection and good adaptability. Experiments evince this algorithm is a good feature detection method.
