Neste trabalho, propomos um método de análise digital do estado de conservação de uma tela, a fim de resolver algumas dificuldades relacionadas com a reintegração pictórica de pinturas que apresentam um número excessivo de diferentes lacunas em termos de tamanho e comprimento. O estudo de caso concreto é um óleo sobre tela de pequena dimensão realizado por um artista desconhecido, onde as múltiplas áreas com lacunas se caracterizam por bordos complexos, difíceis de analisar, classificar e de localizar graficamente. Requeriam uma avaliação cuidadosa do método a ser utilizado durante a intervenção de reintegração pictórica. Através do uso de métodos de análise de imagem, extraímos semi-automaticamente o gráfico do estado de conservação, trazendo diferentes propostas operacionais virtuais.
This work proposes a methodology of digital analysis of the state of conservation of a canvas painting to solve difficulties related to the pictorial reintegration of paintings that present an excessive number of different lacunae in terms of size and extent. The case study is related to the small-size oil on canvas painting executed by an unknown artist, where the lacunae were challenging to analyze and localize graphically. Therefore, it required a careful evaluation of the approach to be used during the pictorial reintegration intervention. Using an image analysis method, based on the semi-automatic extraction approach, the state of conservation’s graphic relief outlining different virtual operating proposals was obtained.

Abstract
This work proposes a methodology of digital analysis of the state of conservation of a canvas painting to solve difficulties related to the pictorial reintegration of paintings that present an excessive number of different lacunae in terms of size and extent. The case study is related to the small-size oil on canvas painting executed by an unknown artist, where the lacunae were challenging to analyze and localize graphically. Therefore, it required a careful evaluation of the approach to be used during the pictorial reintegration intervention. Using an image analysis method, based on the semi-automatic extraction approach, the state of conservation’s graphic relief outlining different virtual operating proposals was obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
