基于潜空间扩散模型的创意绘画

Creative Painting with Latent Diffusion Models

NVIDIA(英伟达)

摘要:

近年来,艺术绘画取得了重大进展。潜空间扩散模型(LDMs)利用自编码器将原始图像与压缩的潜空间连接起来,并以交叉注意增强的U-网作为扩散的主干,实现了稳定且高繁殖力的图像生成。在本文中,我们专注于提高当前LDM的创造性绘画能力在两个方向,文本条件扩展和模型再训练与Wikiart数据集。通过文本条件扩展,用户的输入提示扩展了丰富的上下文知识,更深入地理解和解释提示。维基艺术数据集包含近400年来由1,000多位着名艺术家绘制的80 K着名艺术品,风格和流派丰富。通过再培训,我们能够要求这些艺术家在现代主题上绘制新颖和创造性的绘画。通过与原模型的直接对比,证明了该模型的创造性和艺术性。

英文摘要:

Artistic painting has achieved significant progress during recent years. Using an autoencoder to connect the original images with compressed latent spaces and a cross attention enhanced U-Net as the backbone of diffusion, latent diffusion models (LDMs) have achieved stable and high fertility image generation. In this paper, we focus on enhancing the creative painting ability of current LDMs in two directions, textual condition extension and model retraining with Wikiart dataset. Through textual condition extension, users' input prompts are expanded with rich contextual knowledge for deeper understanding and explaining the prompts. Wikiart dataset contains 80K famous artworks drawn during recent 400 years by more than 1,000 famous artists in rich styles and genres. Through the retraining, we are able to ask these artists to draw novel and creative painting on modern topics. Direct comparisons with the original model show that the creativity and artistry are enriched.
