摘要
介绍焊缝射线底片分级系统中缺陷识别的三种滤噪预处理方法,即改进的σ滤波算法、非均质扩散算法以及基于形态学的M滤波算法。采用这些算法对底片图象进行预处理,得到了明显的滤噪效果。
Three image preprocessing methods for noise filtering in the grading system for X-ray films of weld defects were presented. They were a filtering algorithm, nonhomogeneous diffusion algorithm and morphology-based M filtering algorithm. The methods were applied to preprocessing of X-ray film images and results were sat-isfactory.
