• Abstract: We introduce SLayR, Scene Layout Generation with Rectified flow, a novel transformer-based model for text-to-layout generation which can then be paired with existing layout-to-image models to produce images. SLayR addresses a domain in which current text-to-image pipelines struggle: generating scene layouts that are of significant variety and plausibility, when the given prompt is ambiguous and does not provide constraints on the scene. SLayR surpasses existing baselines including LLMs in unconstrained generation, and can generate layouts from an open caption set. To accurately evaluate the layout generation, we introduce a new benchmark suite, including numerical metrics and a carefully designed repeatable human-evaluation procedure that assesses the plausibility and variety of generated images. We show that our method sets a new state of the art for achieving both at the same time, while being at least 3x times smaller in the number of parameters.

  Diffusion models have been recognized for their ability to generate images that are not only visually appealing but also of high artistic quality. Previous methods primarily focus on UNet-based models (e.g., SD1.5 and SDXL), and limited effort has explored Multimodal Diffusion Transformers (MM-DiTs) Inherit the advantages of MM-DiT, we use a separate set network weights to process the image and text modalities. We contribute a large-scale layout dataset, named LayoutSAM, which includes 2.7 million image-text pairs and 10.7 million entities.

  Current personalization methods can invert an object or concept into the textual conditioning space and compose new natural sentences for text-to-image diffusion models. We propose a novel approach that leverages the step-by-step generation process of diffusion models, which generate images from low to high frequency information. We apply ProSpect in various personalized attribute-aware image generation applications, such as image-guided or text-driven manipulations of materials, style, and layout.

  We propose a diagnostic benchmark for layout-guided image generation that examines four categories of spatial control skills: number, position, size, and shape. Next, we propose IterInpaint, a new baseline that generates foreground and background regions step-by-step via inpainting. We show comprehensive ablation studies on IterInpaint, including training task ratio, crop&paste vs. repaint, and generation order.

  We propose a new framework for conditional image synthesis from semantic layouts of any precision levels. The framework naturally reduces to text-to-image (T2I) at the lowest level with no shape information, and it becomes segmentation-to-image (S2I) at the highest level. We introduce several novel techniques to address the challenges coming with this new setup.

  We address the problem of scene layout generation for diverse domains such as images, mobile applications, documents, and 3D objects. We propose LayoutTransformer, a novel framework that leverages self-attention to learn contextual relationships between layout elements. Our framework allows us to generate a new layout either from an empty set or from an initial seed set of primitives, and can easily scale to support an arbitrary of primitives per layout.
