WorldSculpt is a framework that reconstructs cluttered scenes from grounded videos into compositional per-object meshes, enabling interactive 3D world generation and editing.
This paper argues that vanilla conditional diffusion models fundamentally fail at compositional generation when the target distribution is out-of-distribution, due to score estimation error, and that inference-time corrections cannot fully compensate.
This paper introduces BiDPO, a framework that enhances text-to-image models for complex compositional prompts through preference-based fine-tuning and region-level guidance, achieving state-of-the-art results on compositional fidelity benchmarks.
TILT is a training-free framework that improves compositional generation in diffusion models by using a model-intrinsic reward to align sampling trajectories at test time, enhancing fidelity to complex prompts without external supervision.
