Towards Realistic Open-Vocabulary Remote Sensing Segmentation: Benchmark and Baseline

Bingyu Li, Da Zhang, Haocheng Dong, Junyu Gao, Tao Huo, Xuelong Li, Zhiyuan Zhao

OVRSISBenchV2 provides a more realistic and challenging benchmark for open-vocabulary remote sensing segmentation, where the Pi-Seg baseline achieves strong performance through positive-incentive noise.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

OVRSISBenchV2 substantially expands scene diversity, semantic coverage, and evaluation difficulty beyond prior work, and Pi-Seg delivers strong and consistent results particularly on the more challenging OVRSISBenchV2 benchmark.

C2weakest assumption

That the manually constructed OVRSIS95K dataset and selection of 10 downstream datasets, along with the 35+128 categories, accurately capture realistic geospatial application demands without selection bias or limited diversity in scenes and sensors.

C3one line summary

OVRSISBenchV2 is a realistic benchmark expanding scene and category coverage for open-vocabulary remote sensing segmentation, with Pi-Seg baseline showing strong transfer via positive-incentive noise perturbations.
