Abstract

fetched live from OpenAlex

Augmented Reality (AR) is the act of overlaying 3D virtual objects into a real-world scene. Using robust computer vision algorithms, it is possible to perform AR using only a single video camera. However, these algorithms are very computationally expensive, and most proposed systems have to sacrifice accuracy for speed. Graphics Processing Units (GPUs), originally designed to power graphics-intensive 3D video games and now commonplace on most gaming PCs, can also be used for general purpose computations. We developed a computer vision-based AR system accelerated by a single GPU, allowing robust feature detection and matching to be performed in every frame. We conducted performance evaluations in both indoor and outdoor environments, with parameters optimized for maximum possible accuracy of recovered poses. Our AR system achieves a stable 10-12 frames per second at 640480 resolution on a laptop.

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.

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.
