Abstract

fetched live from OpenAlex

Conventional motion estimation used in rate-distortion (RD) optimized video coding is formulated for an error-free environment. Special considerations have to be made when transmitting video in lossy networks. In this paper we demonstrate a novel method of weighting the distortion used in RD optimized motion compensated prediction. By determining an appropriate weighting factor, motion vectors are biased towards macroblocks that have less influence on the motion propagation path. We therefore propose tracking the influence that each macroblock has along the motion propagation path to determine the weights. When combined with random Intra Updating considerable performance improvements are unveiled in comparison with state of the art robust video schemes.

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.
