KRMARO: Aerial Detection of Small-Size Ground Moving Objects Using Kinematic Regularization and Matrix Rank Optimization
Bibliographic record
Abstract
Detecting moving objects has been well studied in the past due to its importance in computer vision applications. Nevertheless, in aerial imagery, the small sizes of moving objects and the camera motion present challenges to existing well-known detection methods. Most moving object detection methods have reported either high true detection rates associated with high false-detection rates, or low false-detection rates at the expense of lowering true detection rates. This paper proposes a novel method, Kinematic Regularization and Matrix Rank Optimization (KRMARO), to achieve high true-detection rates and reduce false-detection rates significantly. KRMARO introduces a formulation of the moving objects detection problem that integrates a novel kinematic regularization into the principal component pursuit. This formulation models moving objects as sparse, which is located in regions exhibiting unique kinematic properties, while the background is modeled as a low-rank matrix that is corrupted by this sparse. To solve the former formulation accurately, KRMARO proposes a solution based on the inexact Newton method and the inexact augmented Lagrange multiplier with backtracking behavior. The robustness of KRMARO is verified through testing on DARPA VIVID, UCF aerial action, and VIRAT aerial data sets and then comparing the results with relevant state-of-the-art methods.

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.
