Summary

• What is new: Introducing a method to produce transparent images with latent diffusion models by embedding a ‘latent transparency’ into the model’s latent space.
• Why this is important: Previously, generating transparent images required generating the image first and then applying matting techniques, which can be cumbersome and less effective.
• What the research proposes: LayerDiffusion uses a ‘latent transparency’ method that integrates transparency directly into the latent space of diffusion models, allowing for the direct generation of transparent images or layers.
• Results: The model, trained on 1M image pairs, achieved high-quality transparent image generation, preferred by 97% of users over traditional methods, and producing results on par with commercial assets.
