medXGAN: Visual Explanations for Medical Classifiers through a Generative Latent Space

no code implementations11 Apr 2022 Amil Dravid, Florian Schiffers, Boqing Gong, Aggelos K. Katsaggelos

Despite the surge of deep learning in the past decade, some users are skeptical to deploy these models in practice due to their black-box nature.

Investigating the Potential of Auxiliary-Classifier GANs for Image Classification in Low Data Regimes

no code implementations22 Jan 2022 Amil Dravid, Florian Schiffers, Yunan Wu, Oliver Cossairt, Aggelos K. Katsaggelos

Generative Adversarial Networks (GANs) have shown promise in augmenting datasets and boosting convolutional neural networks' (CNN) performance on image classification tasks.

Anatomy of a superorganism -- structure and growth dynamics of army ant bivouacs

no code implementations18 Oct 2021 Thomas Bochynek, Florian Schiffers, André Aichert, Oliver Cossairt, Simon Garnier, Michael Rubenstein

Beyond unicellular and multicellular organisms, there is a third type of structural complexity in living animals: that of the mechanical self-assembly of groups of distinct multicellular organisms into dynamical, functional structures.

Improving Acquisition Speed of X-Ray Ptychography through Spatial Undersampling and Regularization

no code implementations20 May 2021 Prasan Shedligeri, Florian Schiffers, Semih Barutcu, Pablo Ruiz, Aggelos K Katsaggelos, Oliver Cossairt

To avoid the ill-posedness, we investigate the effect of regularizing the phase retrieval algorithm with image priors for various overlap ratios between the neighboring diffraction patterns.

Disassemblable Fieldwork CT Scanner Using a 3D-printed Calibration Phantom

no code implementations12 Nov 2020 Florian Schiffers, Thomas Bochynek, Andre Aichert, Tobias Würfl, Michael Rubenstein, Oliver Cossairt

The use of computed tomography (CT) imaging has become of increasing interest to academic areas outside of the field of medical imaging and industrial inspection, e. g., to biology and cultural heritage research.

Uncalibrated Deflectometry with a Mobile Device on Extended Specular Surfaces

no code implementations24 Jul 2019 Florian Willomitzer, Chia-Kai Yeh, Vikas Gupta, William Spies, Florian Schiffers, Marc Walton, Oliver Cossairt

We introduce a system and methods for the three-dimensional measurement of extended specular surfaces with high surface normal variations.
