PatternPortrait: Draw Me Like One of Your Scribbles

no code implementations22 Jan 2024 Sabine Wieluch, Friedhelm Schwenker

This paper introduces a process for generating abstract portrait drawings from pictures.

Trace and Detect Adversarial Attacks on CNNs using Feature Response Maps

no code implementations24 Aug 2022 Mohammadreza Amirian, Friedhelm Schwenker, Thilo Stadelmann

The existence of adversarial attacks on convolutional neural networks (CNN) questions the fitness of such models for serious applications.

Radial Basis Function Networks for Convolutional Neural Networks to Learn Similarity Distance Metric and Improve Interpretability

1 code implementation24 Aug 2022 Mohammadreza Amirian, Friedhelm Schwenker

In this paper, we adapt RBF networks as a classifier on top of CNNs by modifying the training process and introducing a new activation function to train modern vision architectures end-to-end for image classification.

PrepNet: A Convolutional Auto-Encoder to Homogenize CT Scans for Cross-Dataset Medical Image Analysis

no code implementations19 Aug 2022 Mohammadreza Amirian, Javier A. Montoya-Zegarra, Jonathan Gruss, Yves D. Stebler, Ahmet Selman Bozkir, Marco Calandri, Friedhelm Schwenker, Thilo Stadelmann

With the spread of COVID-19 over the world, the need arose for fast and precise automatic triage mechanisms to decelerate the spread of the disease by reducing human efforts e. g. for image-based diagnosis.

Binary Classification: Counterbalancing Class Imbalance by Applying Regression Models in Combination with One-Sided Label Shifts

no code implementations30 Nov 2020 Peter Bellmann, Heinke Hihn, Daniel A. Braun, Friedhelm Schwenker

In the current study, we focus on binary, imbalanced classification tasks, i. e.~binary classification tasks in which one of the two classes is under-represented (minority class) in comparison to the other class (majority class).
