LVLMs can self-improve small object grounding using attention patterns

Researchers have developed a novel framework, ACS-Learned, that leverages the internal attention patterns of Large Vision Language Models (LVLMs) to improve the grounding of small objects without requiring fine-tuning. By training a lightweight regressor on these attention maps, the system can predict grounding quality and select the best bounding box from multiple candidates. An even more efficient variant, ACS-Free, ranks candidates based on attention entropy in critical transformer layers, demonstrating significant self-improvement in small object localization on benchmark datasets.
