Researchers at Hasselt University and Flanders Make systematically analyzed synthetic data generation and deep learning training techniques for object detection. Their work provides practical guidelines to improve model generalization from synthetic to real-world images, demonstrating that fine-tuning with a small amount of real data can achieve 83.7 AP.
Key insights
- Randomizing low-level features (e.g., lighting) in synthetic data is more beneficial for generalization to real images than randomizing high-level features (e.g., poses) alone.
- Data augmentation and transfer learning are critical techniques for bridging the domain gap, enabling models to learn more robust features.
- Optimal transfer learning involves retraining not just the detection heads, but also substantial parts or all of the feature detector for best performance.
