Region-Level Policy Optimization for Efficient MLLM Perception
September 16, 2026
This method improves fine-grained MLLM perception by decoupling localization and recognition, which have different resolution requirements. By using a lightweight proposal network to concentrate resolution only on relevant regions, the approach reduces vision-encoding and prefilling costs.
