Diffusion Autoencoders: Toward a Meaningful and Decodable Representation

K. Preechakul, N. Chatthee, S. Wizadwongsa, S. Suwajanakorn

CVPR 2022 (Oral)

Our diffusion-based autoencoders can simultaneously infer compact semantic code and stochastic code from an input image. These codes are useful for downstream tasks and allow near-exact reconstruction. Diff-AE can solve tasks like real-image manipulation without GANs and their error-prone inversion and produces more discriminative latent space than StyleGAN-W.

Nex: Real-time View Synthesis with Neural Basis Expansion

S. Wizadwongsa, P. Phongthawee, J. Yenphraphai, S. Suwajanakorn

CVPR 2021 (Oral)

We present NeX, a new approach to novel view synthesis based on enhancements of multiplane image (MPI) that can reproduce NeXt-level view-dependent effects---in real time. A 1000x speed up from SOTA.
