Abstract
Aerial imagery applications have gained a great interest especially in the area of comprehensive ground activities analysis. One of the key tasks in such applications is moving objects segmentation. Although many efforts have been presented in the literature that claim high true object detection rates, they still suffer from high false positive rates. This paper focuses on maintaining a high true positive detection rates while significantly reducing the false positive detection rates. To achieve this goal, this paper proposes a novel method that integrates matrix recovery concept with physical spring model to drastically reduce false detections. The proposed method segment all candidate moving objects by recovering the low rank matrix, which normally results high false positive detection. To reject false detections, each candidate moving object is modelled as a mass suspended by system of springs, such that the forces of springs attached to false detections is negligible whereas the forces of springs attached to a true moving object will be significant in response to the object motion. The results show that the proposed method, compared to other current state-of-the-art methods, achieved better true positive rates while drastically lowering the false positive rates.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
