Outline

This study aims to apply artificial intelligence models to satellite-based remote sensing, focusing specifically on the use of raw, unprocessed data. We developed a simulation workflow that generates raw-like data based on high-resolution L1 images and applied deep learning models to object detection and classification tasks. We trained YOLOv11n and YOLOX-S models on the raw and L1 datasets, respectively, to compare their performance and analyzed them using explainability tools. While both models demonstrated similar performance at low confidence levels, the model trained on raw data struggled to identify object boundaries at high confidence levels.

Takeaways, Limitations

Takeaways:
It suggests the possibility of developing satellite-mounted AI models that directly utilize raw data.
Analyze the causes of performance degradation of raw data-based object detection models and suggest directions for improvement (outline improvement).
We present a methodology for systematically evaluating raw data-based model performance through a simulation workflow.
Limitations:
Raw data-based models struggle to identify object boundaries with high confidence.
Further architectural improvements (outline method) are needed.
Uses simulated data rather than actual satellite raw data.
