This interim report covers the activities of the Working Group 3 (WG3) of "Colour and Space in Cultural Heritage" (www.cosch.info), the COST Transdomain Action TD1201, supported by European Cooperation in Science and Technology CoST
between 2012 – 2016. The report covers the period from 2012 to 2014. The ubiquity of algorithms embedded in everyday life for many who use technology has not, yet, allowed the non-expert users of systems any insight into their function and use. The work of this targeted workgroup seeks to assess, formalise and explain the range of algorithms in use in systems within cultural heritage. Certainly at times for the non-expert user of certain applications it is not apparent what algorithm is being used, and most importantly why it is being used.
This paper aims to introduce a range of algorithms currently used in cultural heritage acquisition and measurement systems, offering explanations, and looking to develop recommendations and guidelines for use, depending on minimal spatial resolution and uncertainty values specified amongst a range of considerations; to inform users of the potential, output, constraints, preconditions and practical aspects related to the use of algorithms and procedures used to process digital data (both spectral and spatial data)and most importantly
to structure knowledge about algorithms and procedures used in DCH in an ontology laying a foundation for an optimised and adapted use of algorithms and procedures for processing digital data by cultural heritage professionals.
