摘要

The quantitative morphological analysis of a painting surface allows to evidence form defects and to study, thus, their influence on the stability of the paint and preparatory layers, as well as of the support. Therefore a three-dimensional survey can be very useful in planning the restoration intervention of a painting. In this work we present the results of the surface analysis carried out on the painting "Ultima Cena" by Giorgio Vasari. This panel painting is severely affected by paint film wrinkling produced as a consequence of the flood that occurred in Florence in 1966. Our analysis, accomplished to quantify the lengthening of the paint layer with respect to the one of the support in order to plan the restoration intervention, was performed on 25 profiles separated each by 10 cm in order to cover the whole painting surface. A data analysis, based on morphological filtering named "Rolling Ball" transformation, was used to evaluate the lengthdifference between the paint layer and the panel support along each profile.
