Abstract

fetched live from OpenAlex

This paper presents a study of feature-based approaches such as SIFT, SURF and ORB as a basis for markerless methodologies for creating augmented reality. In feature-based tracking methods, the target region is represented and tracked in the feature space. A discriminative and repeatable feature description is required to depict local structures according to the information from the spatial neighborhood pixel patterns. The feature representation is invariant to changes in viewing conditions such as scale, orientation and contrast. By matching the feature descriptors from different images, the same region can be detected according to the correspondence relationships between them. Using homography relations, the graphical objects can then be overlaid on the selected region which can be translated and rotated according to relationships between the matched regions.

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.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
