Abstract

fetched live from OpenAlex

One of the major problems in low-bandwidth telerobotics applications is determining what visual data is sufficient to allow the operator to successfully perform a task. When the available bandwidth is extremely low, we must severely restrict the data being transmitted. For very-low-bandwidth applications, displaying certain types of features, such as edges in indoor navigation applications, allows for successful completion of the operator's task. As the available bandwidth increases, the operator can be presented with more information than just the edge features. Using simple overlay techniques to overlay a low-frame-rate video stream on a high-frame-rate edge feature stream provides the operator with more information about the environment. Registering the video data with the moving edge data poses a significant problem. In this paper, we propose to use simple motion estimation techniques based on the edge image stream to estimate the motion of the edge images and use this data to register the slower frame-rate video stream to the edge feature stream. Using these simple estimation techniques allows us to perform the video stream registration quickly as the edge feature data is being presented to the operator.

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.
