FOCUS: Optimal Control for Multi-Entity World Modeling in Text-to-Image Generation

Eric Tillmann Bill, Enis Simsar, Thomas Hofmann

Text-to-image (T2I) models excel on single-entity prompts but struggle with multi-entity scenes, often exhibiting attribute leakage, identity entanglement, and subject omissions. W…

SHYI: Action Support for Contrastive Learning in High-Fidelity Text-to-Image Generation

Tianxiang Xia, Lin Xiao, Yannick Montorfani +3

In this project, we address the issue of infidelity in text-to-image generation, particularly for actions involving multiple objects. For this we build on top of the CONFORM framew…
