Abstract

fetched live from OpenAlex

Augmented reality is a young but very active research area. It is considered a variant of virtual reality. In virtual reality, the user is immersed completely in the virtual scene; whereas in an augmented reality system, the user can see the real scene with the virtual object superimposed onto the real scene. Registration in augmented reality aligns the virtual object with the real scene in 3D. The use of computer vision techniques for registration is an ideal method to accomplish this. In this thesis, a computer vision-based interactive object registration system was developed for augmented reality. In this system, the user can register 3D virtual object onto real images by reconstructing the registration plane. The registration process is semi automatic and only needs intuitive mouse clicking. Experiments show that the system is easy to use and has very good practical registration accuracy.

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.
