Abstract

fetched live from OpenAlex

A more realistic Virtual and Augmented Reality is promised by the emergence of Light Field (LF) technology. Considering LF technology benefits come with an exponential increase in the amount of data required as well as the complexity of view access, the need for efficient compression and random access schemes is essential. In this study, a novel and efficient pseudo-sequence based LF video compression scheme is proposed that offers the best trade-off between coding and access complexity. The philosophy behind our proposed prediction structure is maximally utilizing the low-level frames in hierarchy prediction structure to achieve better random access at a minimal expense of compression efficiency.

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.

Full frame distilled prediction

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.
