- Abstract
- In this study, to automatically detect defects shown in infrared thermography, the optimal threshold analyzedby the Otsu algorithm was applied to infrared thermography to obtain binarized images that are easy todistinguish with the naked eye. Automatic detection was performed using Matlab bwboundaries function tool. A study was conducted to improve defect detection by recognizing defects and marking the boundariesaround the defect area. Consequently, an automatic inspection method using a non-destructive inspectiontechnology was presented to apply a method that can inspect all products in the process of producing plastic(POM) products
