Abstract
The authors propose a framework for binary classification of challenging objects (e.g. incomplete, partial occluded, background over-lapped, scaled, outdoor) in surveillance video. The framework uses feature binding of MPEG-7 visual descriptors via chaotic series simulation. Diverse video objects are tested in multiple binary classifiers for generic classes (e.g. has_person, has_group_of_persons, has_vehicle and has_unknown). Object classification accuracy is verified with both low- and high-dimensional chaotic series-based feature binding. With high-dimensional chaotic series simulation: (i) the classification accuracy significantly improves on average, 83% compared with the 62% with the original MPEG -7 visual descriptors; (ii) ‘vehicle’ objects are clustered well, which leads to above 99% accuracy for only vehicles against other objects; and (iii) drifts in high-dimensional chaotic series, because of transient, allow the training feature vector to include subtle variations in MPEG-7 descriptor coefficients for video objects in a class. A higher variance in training feature vector, using high-dimensional chaotic series simulation, manifests these subtle variations.

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
