Spherical-to-ERP Epipolar Rectification for Single-Axis Disparity in 360 Stereo
Sahereh Obeidavi, Dieter Landes
Omnidirectional stereo images provide full-surround perception but violate the geometric assumptions of classical disparity estimation: in spherical or fisheye views, epipolar corr…
Text-to-Image Generation for Vocabulary Learning Using the Keyword Method
Nuwan T. Attygalle, Matjaž Kljun, Aaron Quigley +9
The 'keyword method' is an effective technique for learning vocabulary of a foreign language. It involves creating a memorable visual link between what a word means and what its pr…
Improved Models for Media Bias Detection and Subcategorization
Tim Menzner, Jochen L. Leidner
We present improved models for the granular detection and sub-classification news media bias in English news articles. We compare the performance of zero-shot versus fine-tuned lar…
Analyzing Multimodal Interaction Strategies for LLM-Assisted Manipulation of 3D Scenes
Junlong Chen, Jens Grubert, Per Ola Kristensson
As more applications of large language models (LLMs) for 3D content for immersive environments emerge, it is crucial to study user behaviour to identify interaction patterns and po…
Investigations on Algorithm Selection for Interval-Based Coding Methods
Tilo Strutz, Nico Schreiber
There is a class of entropy-coding methods which do not substitute symbols by code words (such as Huffman coding), but operate on intervals or ranges. This class includes three pro…
Privacy-Preserving Multi-Center Differential Protein Abundance Analysis with FedProt
Yuliya Burankova, Miriam Abele, Mohammad Bakhtiari +28
Quantitative mass spectrometry has revolutionized proteomics by enabling simultaneous quantification of thousands of proteins. Pooling patient-derived data from multiple institutio…
Experiments in News Bias Detection with Pre-Trained Neural Transformers
Tim Menzner, Jochen L. Leidner
The World Wide Web provides unrivalled access to information globally, including factual news reporting and commentary. However, state actors and commercial players increasingly sp…
Which Country Is This? Automatic Country Ranking of Street View Photos
Tim Menzner, Jochen L. Leidner, Florian Mittag
In this demonstration, we present Country Guesser, a live system that guesses the country that a photo is taken in. In particular, given a Google Street View image, our federated r…
Enhanced Color Palette Modeling for Lossless Screen Content Compression
Hannah Och, Shabhrish Reddy Uddehal, Tilo Strutz +1
Soft context formation is a lossless image coding method for screen content. It encodes images pixel by pixel via arithmetic coding by collecting statistics for probability distrib…
Text Entry Performance and Situation Awareness of a Joint Optical See-Through Head-Mounted Display and Smartphone System
Jens Grubert, Lukas Witzani, Alexander Otte +3
Optical see-through head-mounted displays (OST HMDs) are a popular output medium for mobile Augmented Reality (AR) applications. To date, they lack efficient text entry techniques.…
Image Segmentation For Improved Lossless Screen Content Compression
Shabhrish Reddy Uddehal, Tilo Strutz, Hannah Och +1
In recent years, it has been found that screen content images (SCI) can be effectively compressed based on appropriate probability modelling and suitable entropy coding methods suc…
Improved Screen Content Coding in VVC Using Soft Context Formation
Hannah Och, Shabhrish Reddy Uddehal, Tilo Strutz +1
Screen content images typically contain a mix of natural and synthetic image parts. Synthetic sections usually are comprised of uniformly colored areas and repeating colors and pat…
VocabulARy: Learning Vocabulary in AR Supported by Keyword Visualisations
Maheshya Weerasinghe, Verena Biener, Jens Grubert +4
Learning vocabulary in a primary or secondary language is enhanced when we encounter words in context. This context can be afforded by the place or activity we are engaged with. Ex…
Efficient Error-Tolerant Quantized Neural Network Accelerators
Giulio Gambardella, Johannes Kappauf, Michaela Blott +4
Neural Networks are currently one of the most widely deployed machine learning algorithms. In particular, Convolutional Neural Networks (CNNs), are gaining popularity and are evalu…
Effects of Depth Layer Switching between an Optical See-Through Head-Mounted Display and a Body-Proximate Display
Anna Eiberger, Per Ola Kristensson, Susanne Mayr +2
Optical see-through head-mounted displays (OST HMDs) typically display virtual content at a fixed focal distance while users need to integrate this information with real-world info…
Comparison of System Call Representations for Intrusion Detection
Sarah Wunderlich, Markus Ring, Dieter Landes +1
Over the years, artificial neural networks have been applied successfully in many areas including IT security. Yet, neural networks can only process continuous input data. This is…
A fast-switching magnet serving a spallation-driven ultracold neutron source
S. Ahmed, E. Altiere, T. Andalib +47
A fast-switching, high-repetition-rate magnet and power supply have been developed for and operated at TRIUMF, to deliver a proton beam to the new ultracold neutron (UCN) facility.…
