Abstract

fetched live from OpenAlex

Pattern-based augmented reality systems are considered the most promising approach for accurately registering virtual objects with real-time video feeds. The problem with existing solutions is the lack of robustness to partial occlusions of the pattern, which is important when attempting natural interactions with the virtual objects. This paper describes a fast and accurate vision-based pattern tracking system that allows for autocalibrated 3D augmentations of virtual objects onto known planar patterns. The tracking system is shown to be robust to changes in pattern scale, orientation, and most importantly partial occlusions. A method to detect a hand over top of the pattern is then described, along with a method to render the hand on top of the virtual objects. 1.

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.
