Processamento de imagem digital (PID) como meio de análise, documentação e monitorização da corrosão do aço de carbono aplicado na escultura de Gonçalo Jardim
Abstract
This article aims to present a non-invasive monitoring of the corrosion process of Gonçalo Jardim‘s steel sculpture through the digital image processing system. This research had as main objective to develop an algorithm that treats the information of several local functions of the morphology of the corrosion, through the extraction of quantitative parameters of the image that express this information. For this purpose, the absolute mean value of the entropy of the images was calculated, which evaluates the evolution of the morphology of the corrosion of the sculpture in long term, in order to document it and to analyse if there is maintenance or increase of the corrosion with the passage of time and, in the latter case, in what proportion.
