Abstract

This paper on Conservation of Cultural Heritage explores the use of spatial analysis functions for feature 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.

Keywords: Painting conservation, Spatial analysis, Neighbourhood statistics, Feature extraction, Thangka
