A use-case spotlight on the Daxinzhuang H690 pottery challenge: two-sided images of nearly 20,000 sherds drew 94 submissions, but only two teams reached museum-table verification and the best result yielded 78 confirmed pairs, showing why image retrieval should narrow the search while clay fabric, curvature, and fracture continuity retain the final vote.
