# Synset Signset Germany

<!-- Provide a quick summary of the dataset. -->
The <em>Synset Signset Germany</em> dataset addresses the task of traffic sign recognition in Germany. It contains a total of 105,500 images of 211 different
German traffic sign classes, including newly published (2020) and thus comparatively rare traffic signs. The subset of the first 43 classes in the dataset aims to represent 
a “synthetic twin” of the well-known [GTSRB](https://ieeexplore.ieee.org/abstract/document/6033395) dataset.
