Researchers have developed PR-OVD, a novel framework designed to improve open-vocabulary object detection (OVD) by better preserving the capacity for recognizing new categories. Traditional OVD methods often bias towards base categories, leading to a compression of novel concepts and inaccurate confidence scores. PR-OVD addresses this by partitioning visual and textual embeddings into base, novel, and background categories, thereby preventing irrelevant information from contaminating category-specific representations. The framework also refines these partitions to sharpen decision boundaries and uses a Structure Prompt (SP) to provide robust visual anchors for novel categories, showing significant improvements on OVD benchmarks.
