Tear feature extraction with spatial analysis: A thangka case study

Abstract: This paper on Conservation of Cultural Heritage explores the use of spatial analysis functions for fe ature extraction. The study evaluates the performance of neighbourhood functions for the delimitation of a tear in a thangka painting. The pathology area was documented with a non-conventional technique in painting conservation.

“…In more recent years, the development of low-cost and easy-to-use Geographic Information System software including spatial attributes and mapping elements, has made it possible to use this technology for non-geographic projects. From relatively large areas, GIS has been used on mobile artifacts; especially in Italy, Spain and Portugal, experimentation on the statistical analysis of the degradation of painted canvas and tables has started [ 12 , 13 , 14 , 15 ]. Two GIS systems were used for these experiments: QGIS ® —free and open-source, and ArcGIS ® , proprietary software of Esri ® .…”

“…Análisis cuantitativo de las lagunas: aplicación del QGIS® En las últimas décadas, se han empezado a desarrollar estudios sobre la aplicación de Sistemas de Información Geográfica (SIG) al estudio y análisis de pinturas murales (Schmid 2000: 221-238;Henriques, et al 2009: 13-15) y pinturas de caballete (Fuentes Porto 2010). Los SIG son programas informáticos utilizados en Geografía y que, aplicados a la disciplina de la Conservación y Restauración, permiten el análisis y cuantificación de lagunas en obras bidimensionales mediante la herramienta de georreferenciación (Henriques, et al 2015: 97-102;Bailão, et al 2016: 6-19;Cardeira, et al 2017: 159-171;Henriques et al 2019: 38-41).…”
