| Content Summary | This paper approaches the non-destructive analysis of corrosion damage by testing and evaluating several image segmentation schemes for the detection of decay areas. The application test bed for algorithmic evaluation considers stonework surfaces for corrosion damage. Each of the detection approaches handles in a different way the background inhomogeneities. A semi-automated framework for validating the algorithms’ performance is introduced. This framework guarantees reliable and objective estimation of algorithms’ response, while also enabling informed experimental feedback for the design of improved segmentation algorithms. Further to elaborating on the robust points of each segmentation approach, this work also studies the corrosion mechanisms. The latter process involves investigation of the degradation state as reflected by the size of the decay areas and their darkness. The derived assessments closely converge to assessments based on chemical analyses, performed on the same stone surfaces. | en |
