TextCenGen, a novel method that employs cross-attention maps and force-directed graphs, generates images that strategically reserve whitespace for pre-defined text or icon placements, resulting in harmonious text-image compositions.
Özet
The paper introduces TextCenGen, a novel approach to text-to-image (T2I) generation that focuses on creating text-friendly images. Traditional T2I methods often struggle to generate backgrounds that effectively accommodate text or icons, leading to suboptimal visual harmony.
TextCenGen addresses this challenge by employing cross-attention maps and force-directed graphs to dynamically adapt the image composition. Key highlights:
It introduces a novel task of text-friendly T2I generation, with a specialized dataset and evaluation metrics.
The core of TextCenGen is the force-directed cross-attention guidance, which strategically directs the cross-attention map during the denoising process to ensure sufficient whitespace for text or icon placement.
It also implements a spatial excluding cross-attention constraint to maintain a smooth background in the designated text regions.
Experiments show that TextCenGen outperforms existing methods in generating harmonious text-image compositions, as measured by various metrics like CLIP score, saliency map intersection over union, and total variation loss.
The paper demonstrates the effectiveness of TextCenGen in creating visually appealing and integrated text-image layouts, addressing a crucial challenge in graphic design and T2I generation.
