CASAS-PEREZ, María del Carmen  e  SAROCCHI, Damiano. Image Analysis as a Diagnostic Tool for the Conservation State of Works of Art: its Application to a Painting on a Stone Base of the Virgen de Analco, Puebla. Intervención (Méx. DF) [online]. 2012, vol.3, n.6, pp.18-25. ISSN 2007-249X.

For a long time the conservation state of works of art has been made qualitatively by experts, in general resulting in subjective results. A fast, practical and semi-quantitative method to perform this study is to use image analysis, whereby the image is subdivided into areas characterized by the same degree of alteration, determined in a semi-manual way by a restorer and analyzed automatically by software. This methodology has been applied to a painting from Puebla that represents the Immaculate Conception, painted on basalt and using a unique technique. The results provide a semi-quantitative framework of the conservation state of the work of art and show the areas most affected by weathering and aging processes. The method can be a useful tool for studying the degree of conservation of paintings on different support bases.
