Weakly Supervised Virus Capsid Detection with Image-Level Annotations in Electron Microscopy Images

Hannah Kniesel, Leon Sick, Tristan Payer +5

Current state-of-the-art methods for object detection rely on annotated bounding boxes of large data sets for training. However, obtaining such annotations is expensive and can req…

CutS3D: Cutting Semantics in 3D for 2D Unsupervised Instance Segmentation

Leon Sick, Dominik Engel, Sebastian Hartwig +2

Traditionally, algorithms that learn to segment object instances in 2D images have heavily relied on large amounts of human-annotated data. Only recently, novel approaches have eme…

A Survey on Quality Metrics for Text-to-Image Generation

Sebastian Hartwig, Dominik Engel, Leon Sick +6

AI-based text-to-image models do not only excel at generating realistic images, they also give designers more and more fine-grained control over the image content. Consequently, th…

Leveraging Self-Supervised Vision Transformers for Segmentation-based Transfer Function Design

Dominik Engel, Leon Sick, Timo Ropinski

In volume rendering, transfer functions are used to classify structures of interest, and to assign optical properties such as color and opacity. They are commonly defined as 1D or…
