MOSAIC: Multi-object segmentation for assisted image reconstruction

This paper presents a tool targeted at archaeologists and cultural heritage operators. The tool assists the process of reconstructing broken pictorial artifacts from their physical fragments. The fragments are organized into a database indexed on features such as color distribution, shape and texture. The system can be queried using any fragment as the key, and the results are displayed from the most similar to the most dissimilar. The system provides the operator with complete workflow from photoacquisition onwards. The performance has been assessed with computer simulations and a real use case. Two of the simulations are discussed, as well as the real use case, based on an actual XV century fresco that needed reconstruction.
