A take on latency measurement for vision systems
Bibliographic record
Abstract
Latency in augmented vision systems can be defined as the total delay imposed on information propagating through a device with respect to a direct path. Latency is critically important in vision systems as it imposes a delay on reaction time. With the emergence of headborne augmented vision systems for dismounted soldiers and widespread usage of embedded digital processing in vision systems, latency becomes most critical in dynamic operational scenarios. As consequence, latency has been characterized in the recent years for various technologies including AR headsets, VR headsets and pilot helmets with integrated symbology overlay and night vision. These efforts have led to latency requirements that vary according to the application. However, as there is no standardized definition and testing methodology for latency in vision devices, it is difficult to compare latency values across devices and as stated by different manufacturers. We propose that latency be characterized as a set and not as a single value.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
