Keywords: , ,

This research focuses on the implementation of an enhanced corrosion detection algorithm using multispectral imaging techniques and post-processing image filters. Utilizing various combinations of light filters with image enhancement software, we are able to increase the performance of a pixel-wise corrosion detection algorithm in both recall and precision, increasing the F1-Score of rust pixels detected from 0.33 to 0.60. Identification and quantification of corrosion was applied to applications relating to material characterization and automotive diagnostics.
