WUTDet: A 100K-Scale Ship Detection Dataset and Benchmarks with Dense Small Objects

ArXi:2604.07759v1 Announce Type: new Ship detection for navigation is a fundamental perception task in intelligent waterway transportation systems. However, existing public ship detection datasets remain limited in terms of scale, the proportion of small-object instances, and scene diversity, which hinders the systematic evaluation and generalization study of detection algorithms in complex maritime environments. To this end, we construct WUTDet, a large-scale ship detection dataset.
