Spatial Gram Alignment for Ultra-High-Resolution Image Synthesis
Researchers have introduced Spatial Gram Alignment (SGA), a new framework designed to improve ultra-high-resolution image synthesis using large-scale pre-trained Latent Diffusion Models (LDMs). Traditional methods struggle with extreme resolutions due to a conflict between learnability and fidelity, where direct feature distillation can degrade generation quality. SGA addresses this by aligning self-similarities of generative features with foundation model priors, preserving microscopic pixel-level fidelity while ensuring macroscopic structural coherence. AI
