 UV-CoT achieves this by performing preference comparisons between model-generated bounding boxes. It generates preference data automatically, then uses an evaluator MLLM (e.g., OmniLLM-12B) to rank responses, which serves as supervision to train the target MLLM (e.g., LLaVA-1.5-7B). This approach emulates human perception—identifying key regions and reasoning based on them—thereby improving visual comprehension, particularly in spatial reasoning tasks.
