摘要:

我们介绍了StableMaterials,一种生成逼真物理基础渲染(PBR)材料的新方法,该方法将半监督学习与潜在扩散模型(LDMs)相结合。我们的方法利用对抗训练从现有大规模图像生成模型中蒸馏知识,减少对标注数据的依赖,并增强生成的多样性。这种蒸馏方法使生成的材料分布与SDXL模型的图像纹理分布对齐,从而生成不在初始训练数据集中的新材料。此外,我们采用基于扩散的精炼模型来提高样本的视觉质量并实现高分辨率生成。最后,我们蒸馏了一个潜在一致性模型,使其在四步内即可实现快速生成,并提出了一种新的可拼接技术,该技术消除了与较少扩散步数通常相关的视觉伪影。我们详细描述了StableMaterials的架构和训练过程,以及在现有LDM框架中整合半监督训练的方法,并展示了我们方法的优势。与最先进方法的比较评估显示了StableMaterials的有效性,突显了其在计算机图形学及其他领域的应用潜力。StableMaterials可在https://gvecchio.com/stablematerials上公开获取。

英文摘要:

We introduce StableMaterials, a novel approach for generating photorealistic physical-based rendering (PBR) materials that integrate semi-supervised learning with Latent Diffusion Models (LDMs). Our method employs adversarial training to distill knowledge from existing large-scale image generation models, minimizing the reliance on annotated data and enhancing the diversity in generation. This distillation approach aligns the distribution of the generated materials with that of image textures from an SDXL model, enabling the generation of novel materials that are not present in the initial training dataset. Furthermore, we employ a diffusion-based refiner model to improve the visual quality of the samples and achieve high-resolution generation. Finally, we distill a latent consistency model for fast generation in just four steps and propose a new tileability technique that removes visual artifacts typically associated with fewer diffusion steps. We detail the architecture and training process of StableMaterials, the integration of semi-supervised training within existing LDM frameworks and show the advantages of our approach. Comparative evaluations with state-of-the-art methods show the effectiveness of StableMaterials, highlighting its potential applications in computer graphics and beyond.
