Automatic Microstructure Defect Detection of Ti-6Al-4V Titanium Alloy by Regions-Based Graph

In this paper, we propose a simple and efficient approach for microstructure defect detection of Ti-6Al-4V titanium alloy based on image analysis. The proposed approach mimics the way that domain experts identify the defect area, by segmenting material grains via image preprocessing and detecting defects using region-based graph. The preprocessing step is a sequence of image processing techniques ...
