AccDiffusion is an accurate method for higher-resolution image generation without training. The paper addresses the issue of repeated object generation in patch-wise higher-resolution image generation. The authors propose AccDiffusion, which decouples the vanilla image-content-aware prompt into a set of patch-content-aware prompts, each of which serves as a more precise description of an image patch. Additionally, AccDiffusion introduces dilated sampling with window interaction for better global consistency in higher-resolution image generation. Experimental results show that AccDiffusion effectively addresses the issue of repeated object generation and leads to better performance in higher-resolution image generation. The paper also discusses related work, including diffusion models and training-free higher-resolution image generation. The method is evaluated through extensive experiments, demonstrating its effectiveness in generating high-resolution images without object repetition. The paper concludes that AccDiffusion is a promising approach for higher-resolution image generation.AccDiffusion is an accurate method for higher-resolution image generation without training.
