IBISA: Image-Based Identification / Search for Archaeology

Résumé

IBISA (Image-Based Identification/Search for Archaeology) is a research project supported by the French CNRS. The corresponding software tool manages databases of digital images of archaeological objects, and allows the user to perform searches by examples. For now, the system works with ancient (greek, roman) coins, and the generalization to medieval tiles is under progress. IBISA was designed to help the user decide, from their images, if two objects are either the same, come from the same matrix, share resemblance in style, or are completely different. It uses computer vision methods to make this decision while getting rid of the viewing conditions when searching for similarities in the databases. First, a segmentation method based on active contours extracts the useful part of each image from its background context. Then, a registration method based on the Fourier-Mellin transform sorts the images by similarity, canceling any translation, rotation, or zoom inherent to the photography.
