SIDAR: Synthetic Image Dataset for Alignment & Restoration
Monika Kwiatkowski, Simon Matern, Olaf Hellwich
Image alignment and image restoration are classical computer vision tasks. However, there is still a lack of datasets that provide enough data to train and evaluate end-to-end deep…
Content-Based Landmark Retrieval Combining Global and Local Features using Siamese Neural Networks
Tianyi Hu, Monika Kwiatkowski, Simon Matern +1
In this work, we present a method for landmark retrieval that utilizes global and local features. A Siamese network is used for global feature extraction and metric learning, which…
Image-based Detection of Surface Defects in Concrete during Construction
Dominik Kuhnke, Monika Kwiatkowski, Olaf Hellwich
Defects increase the cost and duration of construction projects as they require significant inspection and documentation efforts. Automating defect detection could significantly re…
A modular framework for object-based saccadic decisions in dynamic scenes
Nicolas Roth, Pia Bideau, Olaf Hellwich +2
Visually exploring the world around us is not a passive process. Instead, we actively explore the world and acquire visual information over time. Here, we present a new model for s…
Learning Disentangled Expression Representations from Facial Images
Marah Halawa, Manuel Wöllhaf, Eduardo Vellasques +2
Face images are subject to many different factors of variation, especially in unconstrained in-the-wild scenarios. For most tasks involving such images, e.g. expression recognition…
Iterative Bilateral Filtering of Polarimetric SAR Data
Olivier D'Hondt, Stéphane Guillaso, Olaf Hellwich
In this paper, we introduce an iterative speckle filtering method for polarimetric SAR (PolSAR) images based on the bilateral filter. To locally adapt to the spatial structure of i…
