RiCL is a self-supervised learning framework for pre-training radar object detectors, leveraging unlabeled data by exploiting temporal consistency and inherent radar target proposals. The framework enables models to achieve comparable performance to fully supervised methods using only 20% of labeled data on the CARRADA dataset.
Key insights
- Radar's inherent temporal consistency and direct object proposals (target lists) can be effectively leveraged as self-supervision signals for pre-training.
- Self-supervised learning can be successfully adapted to non-visual sensor modalities by exploiting domain-specific characteristics rather than directly applying computer vision techniques.
- Pre-training the entire object detection pipeline, including backbone, neck, and head components, leads to more effective feature learning and better detection performance.
