Airborne Infrared Observations of Research Vessel Quest
Bibliographic record
Abstract
Defence Research and Development Canada-Atlantic conducted co-operative infrared (IR) surveillance of research vessel Quest from the air in October 2006 near Halifax harbour. A Canadian Forces Military Patrol Aircraft imaged the Quest in the mid-wave IR band using the Wescam MX-20 IR camera. The Quest cruised along headings such that the sun's azimuthal position was directly astern, perpendicular, and at 45 to the ship heading. For each of the ship-sun orientations, the aircraft executed a flight pattern that consisted of starboard and port passes that transected the Quest at nominal altitudes of 30m and 300m. An additional pass along the ship heading from stern to bow was made at an altitude of 150m. Wide field-of-view IR images were collected from ranges typically exceeding 5 km with a 640 512 pixel resolution. From the digital video, we have extracted the background radiance and the total contrast signature of the Quest for the various ship-sun-pass configurations. The background sky-to-sea profiles reveal a strong increase in mid-wave IR sea radiance with steepening viewing angle. The total contrast mid-wave IR signature has an approximate power-law decay with distance for ranges between about 1-10 km. At close ranges, we qualitatively note contributions to the signature by the radiance from the wake and from reflections of the ship in the sea surface.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
