Progressive Learning of 3D Reconstruction Network from 2D GAN Data

no code implementations18 May 2023 Aysegul Dundar, Jun Gao, Andrew Tao, Bryan Catanzaro

In this work, to overcome these limitations of generated datasets, we have two main contributions which lead us to achieve state-of-the-art results on challenging objects: 1) A robust multi-stage learning scheme that gradually relies more on the models own predictions when calculating losses, 2) A novel adversarial learning pipeline with online pseudo-ground truth generations to achieve fine details.

VecGAN: Image-to-Image Translation with Interpretable Latent Directions

no code implementations7 Jul 2022 Yusuf Dalva, Said Fahri Altindis, Aysegul Dundar

However, while those models cannot be trained end-to-end and struggle to edit encoded images precisely, VecGAN is end-to-end trained for image translation task and successful at editing an attribute while preserving the others.
