Abstract

Damage to the painting cultural heritage is recognized through visual observation, photographic data, and conservation diagnosis records, and technology that accurately understands the degree of change over time can prevent damage and be effectively used for conservation treatment. In this study, a time series analysis was conducted to diagnose and compare the conservation status of the past and the present using the digital image of Hanging Painting of Bongjeongsa Temple, Andong (The Vulture Peak Assembly) with different filming times. Color information was analyzed using a digital image analysis program. The shape information and area of crease, exfoliation of painting layer, loss of background material and contamination were calculated using the Relief, Threshold Switching, Color Mapping in HSV space function. Based on the calculated data, the change pattern was confirmed by comparing the damage that occurred in the same area. Quantitative data such as the area of damage and the length of the object were used together to comprehensively compare and analyze the degree of improvement and change in damage that occurred throughout the work to evaluate the change over time.
