Abstract: In various example embodiments, techniques are provided for detecting surface corrosion on infrastructure. A training dataset that includes images of infrastructure that have at least some surface corrosion is received. A red-green-blue (RGB) color channel-based classifier is optimized, wherein the optimizing selects one or more color indices for pixels and determines one or more bounds for each of the selected color indices that indicate a pixel is a corrosion pixel or non-corrosion pixel. The optimized RGB color channel-based classifier is applied to the images to label corrosion segments in the images and produce a labeled training dataset with labeled corrosion segments. The labeled training dataset is used to train a semantic deep learning model to enable the semantic deep learning model to detect corrosion segments.
