COLLAR: Cascaded Object-Level Latent Refinement for High-Fidelity Conditional Generation
Researchers have introduced COLLAR, a new framework designed to improve object-level control in diffusion models. This method uses a training-free approach that refines object features by expanding the Field-of-View. COLLAR incorporates modules for cross-scale semantic alignment and cyclic feature injection to better integrate local details into the global generation process, aiming to reduce visual artifacts and enhance spatial fidelity.
