Human Pose Estimation from Sparse Inertial Measurements through Recurrent Graph Convolution

no code implementations23 Jul 2021 Patrik Puchert, Timo Ropinski

We propose the adjacency adaptive graph convolutional long-short term memory network (AAGC-LSTM) for human pose estimation from sparse inertial measurements, obtained from only 6 measurement units.

Classifying the classifier: dissecting the weight space of neural networks

1 code implementation13 Feb 2020 Gabriel Eilertsen, Daniel Jönsson, Timo Ropinski, Jonas Unger, Anders Ynnerman

of neural network classifiers, and train a large number of models to represent the weight space.

Total Denoising: Unsupervised Learning of 3D Point Cloud Cleaning

1 code implementation ICCV 2019 Pedro Hermosilla, Tobias Ritschel, Timo Ropinski

We show that denoising of 3D point clouds can be learned unsupervised, directly from noisy 3D point cloud data only.


Training Object Detectors on Synthetic Images Containing Reflecting Materials

no code implementations29 Mar 2019 Sebastian Hartwig, Timo Ropinski

While synthesized data sets can be used to overcome this challenge, it is important that these data sets close the reality gap, i. e., a model trained on synthetic image data is able to generalize to real images.

Net2Vis -- A Visual Grammar for Automatically Generating Publication-Tailored CNN Architecture Visualizations

1 code implementation11 Feb 2019 Alex Bäuerle, Christian van Onzenoodt, Timo Ropinski

To convey neural network architectures in publications, appropriate visualizations are of great importance.

Deep-learning the Latent Space of Light Transport

1 code implementation12 Nov 2018 Pedro Hermosilla, Sebastian Maisch, Tobias Ritschel, Timo Ropinski

Thus, we suggest a two-stage operator comprising of a 3D network that first transforms the point cloud into a latent representation, which is later on projected to the 2D output image using a dedicated 3D-2D network in a second step.

Classifier-Guided Visual Correction of Noisy Labels for Image Classification Tasks

1 code implementation9 Aug 2018 Alex Bäuerle, Heiko Neumann, Timo Ropinski

We thus propose a novel approach that uses the power of pretrained classifiers to visually guide users to noisy labels, and let them interactively check error candidates, to iteratively improve the training data set.
