核心概念
The author proposes a method to enhance text-to-image systems by introducing explicit spatial relations in the training data, leading to significant improvements in image generation quality and generalization to unseen objects.
要約
The content discusses the creation of the Spatial Relation for Generation (SR4G) dataset to improve explicit spatial relationships in text-to-image generation. By fine-tuning Stable Diffusion models with this dataset, the study shows notable enhancements in spatial understanding capabilities and image quality. The results surpass state-of-the-art models, demonstrating the effectiveness of synthetic caption training for spatial relations.
Key points include:
Introduction of SR4G dataset with 14 explicit spatial relations.
Fine-tuning Stable Diffusion models on SR4G leads to improved VISOR metric.
Generalization to unseen objects demonstrated.
Comparison with state-of-the-art pipeline models LayoutGPT and VPGen.
Analysis of biases, performance by triplet frequency, and qualitative evaluation of generated images.
The study highlights the importance of incorporating explicit spatial relations in training data for enhancing text-to-image generation systems.
統計
SR4G contains 9.9 million image-caption pairs for training.
SDSR4G yields up to 9 points improvement in the VISOR metric.
Unseen split includes 8.0k unique captions for evaluation.
