Chaotic Synchronization of MPEG-7 Descriptors for Interpretation in Surveillance Video
Bibliographic record
Abstract
The research in video surveillance is moving towards semantic (i.e., meaning) analysis of the scene contents through high-level descriptions. Chaos theory has been reported to simulate partial functions (i.e., neuronal activity in brain) of the human visual system. In this work, we propose a chaotic synchronization-based method to identify semantic entities in surveillance scenes. MPEG-7 visual descriptors (Ds) are used to extract low-level features of video objects. These objects are generated per video frame by segmentation and tracking. The chaotic synchronization is used to perform feature binding (i.e., group semantically relevant feature elements) from these Ds. The objective is to search for unique numeric descriptions (based on low-level features) to identify semantic entities. The idea of a semantic space is introduced to explain feature binding from multiple features spaces. Subjective result evaluation of our results show the existence of such numeric description for related semantic entities (e.g., male, female, enter, deposit, take object, two person meet)

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
