Resumen

En este trabajo se propone una metodología de análisis digital del estado de conservación de un lienzo con el fin de resolver algunas dificultades relacionadas con la reintegración pictórica de pinturas que presentan un excesivo número de diversas lagunas en términos de tamaño y extensión. El caso de estudio en concreto es un óleo sobre lienzo de pequeño tamaño realizado por un artista desconocido, donde las múltiples áreas con dichas lagunas se caracterizan por bordes complejos difíciles de analizar, clasificar y de localizar gráficamente. Requerían de una evaluación cuidadosa del método a usar durante la intervención de reintegración pictórica. A través del uso de métodos de análisis de imágenes, hemos extraído de forma semiautomática el relieve gráfico del estado de conservación, trazando diferentes propuestas operativas virtuales.
