DeCoRL：面向多图组合的分解式一致性强化学习框架
DeCoRL: Decomposed Consistency Reinforcement Learning for Multi-Image Composition
AI 导读
DeCoRL 提出一种强化学习框架，将多图组合（MICo）的整体一致性拆解为对象级一致性，通过建立参考图间的指令相关对象对应关系，并用基于 VLM 的奖励模型给出对象级细粒度反馈，聚合为多对象一致性奖励来指导 RL 后训练。团队同时推出覆盖 2 至 6 张参考图的 DeCo-Bench 基准，在 DeCo-Bench 与公开的 MICo-Bench 上均取得一致性提升。

Abstract:Multi-image composition (MICo) is a critical yet challenging capability for large-scale image editing models, where consistency degrades rapidly as the number of reference images increases. While supervised fine-tuning (SFT) can equip models with basic MICo ability, it provides only implicit supervision on the composed image and often fails to learn reliable object-level correspondence across multiple references. We propose DeCoRL, a reinforcement-learning (RL) framework that improves MICo consistency by decomposing holistic MICo consistency into object-level consistency. DeCoRL first establishes instruction-relevant object correspondences across reference images and localizes the corresponding regions in the generated image. It then uses a VLM-based reward model trained on single-object consistency annotations to produce fine-grained, object-wise feedback, which is aggregated into a multi-object consistency reward to guide RL post-training. We further introduce DeCo-Bench, a benchmark covering compositions from 2 to 6 reference images. Experiments on DeCo-Bench and the public MICo-Bench demonstrate consistent improvements in MICo consistency.
