A new refinement recipe for NVIDIA's Open-H3-Regenerate-2K aims to better preserve details like facial features and text from an initial draft pass. This alternative approach, dubbed "Keep the Draft," re-noises the upscaled draft to a lower sigma value (0.7) before denoising, allowing approximately 30% of the draft signal to survive. In contrast, NVIDIA's original recipe starts at a higher sigma (0.909), preserving only about 9% of the draft signal, which gives the refinement pass more freedom to alter the image. Both methods maintain similar computational costs and runtime. AI
IMPACT This refinement technique could improve the consistency and detail preservation in AI-generated images, particularly for features like faces and text.
