I built a pipeline that uses multi-infusion of Sentinel-1 satellite imagery and Danish government AIS data, then fine tunes a YOLO V8 model to detect ship bounding boxes. We overlay AIS to identify each vessel by MMSI, dimensions, and destination, and cross reference the most recent AIS points to flag suspicious vessels not appearing in AIS. I showed examples where ships were detected but did not show up in AIS, often like simple offsets, with many such cases. No action was requested from viewers."}
