Refinement via Regeneration: Enlarging Modification Space Boosts Image Refinement in Unified Multimodal Models

Jiayi Guo, Linqing Wang, Jiangshan Wang +6

Unified multimodal models (UMMs) integrate visual understanding and generation within a single framework. For text-to-image (T2I) tasks, this unified capability allows UMMs to refi…
