Abstract

fetched live from OpenAlex

In this paper, an approach for intelligent integration of indoor visual tracking system for event detection and movement is proposed. This surveillance system is composed of a stationary camera and a pan tilt zoom (PTZ) camera, where the two cameras have been intrinsically and extrinsically calibrated. The stationary camera detects events such as fall and wandering using motion-based visual tracking. In this initial study, the PTZ camera tracks and follows the person who triggered the event using intelligent color-based particle filtering which is defined based on the expected dynamics of the scene. The purpose of tracking in view of the PTZ camera is to continuously keep the person in the full view of the camera which can further be processed for identifying details of the person. Preliminary experimental results for camera calibration, event detection, and human tracking are presented to demonstrate the performance of the proposed cooperative hybrid visual tracking system.

Not 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.
