Synthesizing Annotated Image and Video Data Using a Rendering-Based Pipeline for Improved License Plate Recognition

no code implementations28 Sep 2022 Andreas Spruck, Maximilane Gruber, Anatol Maier, Denise Moussa, Jürgen Seiler, Christian Riess, André Kaup

The benefits of the proposed data generation pipeline, especially for machine learning scenarios with limited available training data, are demonstrated by an extensive experimental validation in the context of automatic license plate recognition.

Increasing the Accuracy of a Neural Network Using Frequency Selective Mesh-to-Grid Resampling

no code implementations28 Sep 2022 Andreas Spruck, Viktoria Heimann, André Kaup

Using an extensive experimental evaluation we show that depending on the network architecture and classification task the application of FSMR during training aids the learning process.

3D Rendering Framework for Data Augmentation in Optical Character Recognition

no code implementations27 Sep 2022 Andreas Spruck, Maximiliane Hawesch, Anatol Maier, Christian Riess, Jürgen Seiler, André Kaup

Applying the proposed method, improvements of up to 2. 79 percentage points in terms of Character Error Rate (CER), and up to 7. 88 percentage points in terms of Word Error Rate (WER) are achieved on the subset.

Quality Assurance of Weld Seams Using Laser Triangulation Imaging and Deep Neural Networks

no code implementations27 Sep 2022 Andreas Spruck, Jürgen Seiler, Michael Roll, Thomas Dudziak, Jürgen Eckstein, André Kaup

Due to their special characteristics, the images must be pre-processed to enable the use of a deep neural network.

Motion-Adapted Three-Dimensional Frequency Selective Extrapolation

no code implementations15 Sep 2022 Andreas Spruck, Markus Jonscher, Jürgen Seiler, André Kaup

This proposed extension solves the problem of changing content within the area considered by the 3D-FSE, which is caused by motion within the sequence.

Forensic License Plate Recognition with Compression-Informed Transformers

no code implementations29 Jul 2022 Denise Moussa, Anatol Maier, Andreas Spruck, Jürgen Seiler, Christian Riess

Forensic license plate recognition (FLPR) remains an open challenge in legal contexts such as criminal investigations, where unreadable license plates (LPs) need to be deciphered from highly compressed and/or low resolution footage, e. g., from surveillance cameras.

Frequency-Selective Geometry Upsampling of Point Clouds

no code implementations3 May 2022 Viktoria Heimann, Andreas Spruck, André Kaup

The demand for high-resolution point clouds has increased throughout the last years.

Frequency-Selective Mesh-to-Mesh Resampling for Color Upsampling of Point Clouds

no code implementations17 Mar 2022 Viktoria Heimann, Andreas Spruck, André Kaup

Secondly, we propose to apply a novel Frequency-Selective Mesh-to-Mesh Resampling (FSMMR) technique for the interpolation of the points in 2D.
