Researchers have developed MSPO, a novel semantic calibration framework designed to improve open-world object detection (OWOD). MSPO enhances existing probabilistic objectness models by integrating language priors from known categories. This approach helps distinguish between known objects, objects from unseen categories, and background clutter without converting OWOD into open-vocabulary classification. Experiments on M-OWODB and S-OWODB datasets show that MSPO boosts performance on aggregate metrics and increases mAP on PASCAL VOC by up to 2.7 points, demonstrating the effectiveness of semantic calibration for probabilistic objectness.
