Synset Signset Germany: 21,500 Synthetic Traffic Sign Images

21,500 synthetic images across 43 traffic sign classes produced by FraunhoferIOSB as a 'synthetic twin' to the German Traffic Sign Recognition Benchmark (GTSRB). Each class contains exactly 500 independent images to facilitate balanced training for traffic sign recognition tasks.

Use Cases

• Training image classification models to recognize 43 specific German traffic sign categories
• Benchmarking domain adaptation performance by comparing synthetic results against real-world GTSRB images
• Developing image segmentation algorithms using the synthetic masks associated with the 43 sign classes

Strengths

• 21,500 independent images
• Perfectly balanced with 500 images per class
• Directly maps to the 43 standard GTSRB classes

Limitations

• Synthetic domain gap may affect performance on real-world sensor data
• Restricted to German traffic sign designs
