DARS: Dual-Level Credit Assignment RL with Structured Reasoning for Instruction-Based Image Editing

Instruction-based image editing uses a planner-renderer pipeline: a vision-language model (VLM) first converts the instruction into an edit plan, and a diffusion model then executes that plan. Training such systems with only final-image rewards is inefficient because a poor edit does not reveal whether additional optim...

AnyStyle: A Single LoRA is Sufficient for Image-Guided Style Transfer

AnyStyle is proposed, a streamlined framework for image-guided style transfer that adopts a unified single-adapter paradigm for coherent style capture from the style image and incorporates training-free structural guidance from the content image, thus avoiding complex entanglement between multiple adapters and improvin...
