Abstract Scope |
Diffusion probabilistic models (DPMs) have been wildly successful at image generation across a variety of applications. One weakness of DPMs is the lack of a latent representation that is meaningful and decodable. Recently developed diffusion autoencoders have demonstrated a dual latent space that captures both the high-level semantics and stochastic variation separately. Current diffusion autoencoders are adept at producing multiple versions of an image with the same large scale features (e.g women’s face) but very minor changes (position of individual strands of hair). They are not adept at producing multiple distinct realizations of a microstructure where each image is visually distinct but share common features (such as size and shape distributions). Here we present a novel microstructural diffusional variational autoencoder (MDVAE) with an architecture and latent space designed to properly capture and reproduce the full range of variability in realistic microstructure images. |
