Researchers have introduced a new approach to open-world object counting, addressing the brittleness of current methods by redefining the problem as multi-grained counting. This method explicitly defines the desired granularity of counting through visual exemplars and fine-grained text, including negative prompts, across five distinct levels. To support this, they developed an automatic data-scaling pipeline using 3D synthesis and VLM-based filtering to create KubriCount, the largest dataset for counting tasks, and trained a model called HieraCount that significantly improves accuracy and generalization.
