The application of computer-aided approaches in corrosion control has recently become a challenging issue. However, the majority of researches attain to estimate the decay presence by evaluating
colour and texture alterations. This paper is geared towards investigating non-destructive detection and quantification of stone degradation by using machine vision schemes. The contribution of the current work is 4-fold. Thus, several detection schemes were developed, each handling in a different way the background inhomogeneity. Numerous statistical metrics were introduced to quantify corrosion damage. These metrics mainly consider the decay areas size, spatial distribution, shape and darkness. The potential of several monitoring modalities in determining corrosion attributes is studied, and the corroded areas’ shape features are considered in association with the cleaning and structural state that they represent. http://creativecommons.org/licenses/by/4.0/8th International Symposium on the Conservation of Monuments in the Mediterranean Basin: Monument Damage Hazards & Rehabilitation Technologies Proceedings 8th International Symposium on the Conservation of Monuments in the Mediterranean Basin: Monument Damage Hazards & Rehabilitation Technologies
