Despite the stunning ability to generate high-quality images by recent text-to-image models, current approaches often struggle to effectively compose objects with different attributes and relationships into a complex and coherent scene. We propose T2I-CompBench, a comprehensive benchmark for open-world compositional text-to-image generation, consisting of 6,000 compositional text prompts from 3 categories (attribute binding, object relationships, and complex compositions) and 6 sub-categories (color binding, shape binding, texture binding, spatial relationships, non-spatial relationships, and complex compositions). We further propose several evaluation metrics specifically designed to evaluate compositional text-to-image generation. We introduce a new approach, Generative mOdel fine-tuning with Reward-driven Sample selection (GORS), to boost the compositional text-to-image generation abilities of pretrained text-to-image models. Extensive experiments and evaluations are conducted to benchmark previous methods on T2I-CompBench, and to validate the effectiveness of our proposed evaluation metrics and GORS approach.

本研究提出了T2I-CompBench，这是一个全面的开放式文本成像生成基准测试，包括6000个组合文本提示，分为3个类别和6个子类别，并介绍了几个特定设计的评估度量标准，以评估组合文本到图像生成的效果，并提出了新的生成模型细调和奖励驱动的样本选择（GORS）方法来提高预训练文本到图像模型的组合文本到图像生成能力。
