Synthetic images aid the recognition of human-made art forgeries

no code implementations22 Dec 2023 Johann Ostmeyer, Ludovica Schaerf, Pavel Buividovich, Tessa Charles, Eric Postma, Carina Popovici

In addition, we find that, in line with previous research, the inclusion of synthetic forgeries in the training also enables the detection of AI-generated forgeries, especially if created using a similar generator.

Art Authentication with Vision Transformers

no code implementations6 Jul 2023 Ludovica Schaerf, Carina Popovici, Eric Postma

In recent years, Transformers, initially developed for language, have been successfully applied to visual tasks.

A one-armed CNN for exoplanet detection from light curves

no code implementations12 May 2021 Koko Visser, Bas Bosma, Eric Postma

We propose Genesis, a one-armed simplified Convolutional Neural Network (CNN)for exoplanet detection, and compare it to the more complex, two-armed CNN called Astronet.

Reducing Artificial Neural Network Complexity: A Case Study on Exoplanet Detection

no code implementations27 Feb 2019 Sebastiaan Koning, Caspar Greeven, Eric Postma

Our results show only a non-substantial loss in accuracy compared to the original AstroNet, while reducing training time up to 85 percent.

Light-weight pixel context encoders for image inpainting

no code implementations17 Jan 2018 Nanne van Noord, Eric Postma

In this work we propose Pixel Content Encoders (PCE), a light-weight image inpainting model, capable of generating novel con-tent for large missing regions in images.

Learning scale-variant and scale-invariant features for deep image classification

no code implementations3 Feb 2016 Nanne van Noord, Eric Postma

This leads to the conclusion that encouraging the combined development of a scale-invariant and scale-variant representation in CNNs is beneficial to image recognition performance.

Exploring the influence of scale on artist attribution

no code implementations19 Jun 2015 Nanne van Noord, Eric Postma

Previous work has shown that the artist of an artwork can be identified by use of computational methods that analyse digital images.

Circle-based Eye Center Localization (CECL)

no code implementations15 Jun 2015 Yustinus Eko Soelistio, Eric Postma, Alfons Maes

The CECL method achieved an accuracy of 80. 8% to 99. 4% and ranked first for 2 of the 5 thresholds.
