Cover Image: false-color representation of a fragment of a Roman mosaic depicting a jaguar, part of the floor decoration of a 2nd–3rd century CE domus at the archaeological site of Saltara, Marche (Italy). This mosaic is the focus of the study presented in the article “GIS Approach for Mosaic Tesserae Recognition by Supervised Image Classification” by Vincenzo Alfio et al., which introduces a machine learning-based classification method applied to orthoimages of mosaics. The method categorizes individual tesserae, reduces the time and subjectivity associated with manual digitization, and identifies possible differences in tesserae arrangement and size, providing valuable insights for conservation and analysis.
