Learn Temporal Consistency For Robust Satellite Video Detector
Summary
A new satellite video object detection framework, Temporal Consistency Learning (TCL), addresses limitations in existing methods that struggle with oriented and fine-grained objects and use horizontal bounding boxes. TCL utilizes rich temporal contexts to detect these objects, integrating three modules: temporal and fine-grained feature aggregation (TFA), structure encoding (SE), and temporal consistency constraint (TCC). TFA and TCC ensure consistent representation learning across frames, while SE encodes appearance and structural information for precise recognition. Experiments on the SAT-MTB benchmark show TCL achieves 47.7% mAP, a 4.8% improvement over the baseline, setting a new benchmark for oriented and fine-grained detection accuracy. TCL also enhances existing image-based detectors.
Key takeaway
For Computer Vision Engineers developing satellite video analytics, integrating Temporal Consistency Learning (TCL) can significantly improve detection accuracy for oriented and fine-grained objects. You should consider adopting TCL's framework, particularly its TFA, SE, and TCC modules, to enhance consistent object representation across video frames. This approach offers a 4.8% mAP improvement on benchmarks like SAT-MTB, making it a robust upgrade for your existing image-based detectors.
