SEGA: Spectral-Energy Guided Attention for Resolution Extrapolation in Diffusion Transformers
Researchers have developed SEGA, a novel training-free method to improve the resolution extrapolation capabilities of diffusion transformers used in text-to-image generation. SEGA adaptively scales attention across different frequency components of the latent representation during the denoising process. This approach enhances both the structural coherence and the fine-detail fidelity of generated images at higher resolutions compared to existing methods. AI
