Creative Painting with Latent Diffusion Models
Authors:Xianchao Wu
Artistic painting has achieved significant progress during recent years by applying hundreds of GAN variants. However, adversarial training has been reported to be notoriously unstable and can lead to mode collapse. Recently, diffusion models have achieved GAN-level sample quality without adversarial training. Using autoencoders to project the original images into compressed latent spaces and cross attention enhanced U-Net as the backbone of diffusion, latent diffusion models have achieved stable and high fertility image generation. In this paper, we focus on enhancing the creative painting ability of current latent diffusion models in two directions, textual condition extension and model retraining with Wikiart dataset. Through textual condition extension, users’ input prompts are expanded in temporal and spacial directions 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.
