Abstract
A new fast technique for block-based motion estimation using the simplex technique is presented. Block-based motion estimation is used in several video compression applications and standards. The simplex search is a fast search technique that converges rapidly towards the minimum point in small or irregular search areas. It starts with a certain initial-point configuration and then moves towards the solution through a set of operations. These operations include reflection, expansion, and contraction. The proposed technique was implemented as part of the MPEG-2 encoder and was compared with different search techniques. The results obtained show that the technique has better performance over some existing techniques in terms of computation complexity and motion estimation accuracy.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
