Abstract

fetched live from OpenAlex

This paper proposes a novel tracking strategy that can robustly track a person or other object, within a fixed environment using a pan, tilt, and zoom camera with the help of a pre-recorded image database. We define a set called the minimum camera parameter settings (MCPS) which contains just enough camera states as required to survey the environment for the target. This set of states is used to facilitate tracking and segmentation. The idea is to store a background image of the environment for every camera state in MCPS, thus creating an image database. During tracking camera movements are restricted to states in MCPS (or a version of this set that is augmented to improve smoothness of tracking). Scanning for the target and segmentation of the target from the background are simplified as each current image can be compared with the corresponding pre-recorded background image.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
