Abstract

fetched live from OpenAlex

The problem addressed in this work is the achievement of accurate and real-time detection of target in uncontrolled environments, which are typically characterized by dynamic background and lightning changes. Two main contributions are presented. Starting from a state-of-the-art background subtraction approach based on non-parametric codebook model [1], we first propose some algorithmic improvements leading to a reduced processing time with a slight increase of detection accuracy. Secondly, we developed a method to remove false detections caused by uncovered background areas. At the same time, this proposed algorithm contributes to eliminate most erroneously detected clusters and allows decreasing the background initialization period to a single frame. The analysis demonstrated that the proposed approach constitutes one more step toward efficient and real-time automated video monitoring system for uncontrolled environments.

Full frame distilled prediction

Teacher imitation

Not 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.
