After a four-year project period has ended, the Early Stage Researchers’ work have been demonstrated through several publications and presentations at various conferences. At the time of writing, 46 journal and conference papers have been published, and several are under peer-review. The papers are openly available in Zenodo repository together with data sets collected and analysed for the research (

Some of the results for the three scientific work packages (WP) are presented below:
WP3: Multiscale and multimodal strategies and systems for change capture and tracking of cultural heritage assets: in this WP the ESRs have been working on finding methods and strategies on how to select devices to characterise change in appearance of different materials as different materials encounter different challenges. E.g. stained glasses are transparent, they can easily reflect light, and they are often placed far up in the historical building they are part of – all aspects that make it challenging for imaging. ESR 1 has studied, developed, and tested methods (laboratory, portable, in-situ) to optimize the digitization of stained-glass windows in different scenarios. ESR 8 has developed a robotic arm based RTI acquisition system, a setup to automate and expedite acquisitions while capturing cultural heritage surfaces, allowing the generation of images with light from many different angles, trying to overcome the challenge of shadows covering details when capturing textured objects.
WP4: Computational methods for change studying (characterization, visualisation, and monitoring) of Culture Heritage assets: For the data of change detection to be useful, it is important to find methods to visualize them. Two novel methods for further post-processing of surface data to identify the location of changes and assess them over time or before and after conservation treatment on heritage objects have been implemented by ESR 4. ESR 3 had developed a method for cross-time registration, where 3D models captured at different timeframes, or before and after a modification, are aligned.
WP5: Application: Change during the alteration and conservation of cultural heritage artefacts: What are the needs of a cultural heritage actor when using imaging techniques to monitor artefacts during their alterations? This is one of the questions we have tried to answer in this WP. Together with a conservator, ESR 7 has tested gloss measurement for imaging to quantify appearance changes when removing varnish of gilded painting and frame using various methods, including traditional colorimetry, gloss measurements, and bidirectional reflectance measurements. The varnish removal method was chosen based on the results of this test.
The ESRs of CHANGE have received training in using imaging techniques, multivariate data analysis as well as change measurement. In addition, they have received training in transferrable skills important for their research careers, like research ethics and project management. This was conducted during training schools at the NTNU in Norway, at C2RMF and UBFC in France, HES-SO and SNM in Switzerland, WUT, AFAW and MKJ in Warsaw in Poland, as well as at the Rijksmuseum in the Netherlands. All ESRs have set up a personal career development plan as well as a data management plan with focus on generating open data, increasing the possibilities of exploitation of the CHANGE results.
The ESRs have also conducted several stays (secondments) with different project partners during their project period.
