Image analysis techniques for cultural heritage restoration methods evaluation

In this paper a new approach to assess the efficiency of a cultural heritage restoration method is proposed. A case study for a multi-stage treatment applied to an old wooden smoke-damaged painting is discussed. The restoration procedure is evaluated by analyzing the evolution of several statistical measurements like mean value, standard deviation (STD) and blind image quality assessment (IQA) indexes applied to several selected areas of the cleaned object imageries. The results regarding the restoration assessment suggest the applicability of the proposed method in artwork restoration evaluation.
