Alias-Free Generative Adversarial Networks

7 code implementations NeurIPS 2021 Tero Karras, Miika Aittala, Samuli Laine, Erik Härkönen, Janne Hellsten, Jaakko Lehtinen, Timo Aila

We observe that despite their hierarchical convolutional nature, the synthesis process of typical generative adversarial networks depends on absolute pixel coordinates in an unhealthy manner.

GANSpace: Discovering Interpretable GAN Controls

2 code implementations NeurIPS 2020 Erik Härkönen, Aaron Hertzmann, Jaakko Lehtinen, Sylvain Paris

This paper describes a simple technique to analyze Generative Adversarial Networks (GANs) and create interpretable controls for image synthesis, such as change of viewpoint, aging, lighting, and time of day.

Disentangling Random and Cyclic Effects in Time-Lapse Sequences

1 code implementation4 Jul 2022 Erik Härkönen, Miika Aittala, Tuomas Kynkäänniemi, Samuli Laine, Timo Aila, Jaakko Lehtinen

We introduce the problem of disentangling time-lapse sequences in a way that allows separate, after-the-fact control of overall trends, cyclic effects, and random effects in the images, and describe a technique based on data-driven generative models that achieves this goal.

E-LPIPS: Robust Perceptual Image Similarity via Random Transformation Ensembles

1 code implementation10 Jun 2019 Markus Kettunen, Erik Härkönen, Jaakko Lehtinen

It has been recently shown that the hidden variables of convolutional neural networks make for an efficient perceptual similarity metric that accurately predicts human judgment on relative image similarity assessment.
