Abstract

fetched live from OpenAlex

This letter presents a region-based predictive decoding technique for end-to-end delay reduction in video communications. Video frames are predicted from past video data and displayed before they arrive at the decoder, thereby reducing the end-to-end delay. This problem is similar to whole-frame concealment, so we compare our method to a state-of-the-art whole-frame concealment algorithm. As demonstrated in the letter, our method yields better visual results with peak signal-to-noise ratio gains up to 2.5 dB on sequences with complex and high-intensity motion. These gains are mainly due to motion segmentation and region-based motion prediction.

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.
