Abstract

fetched live from OpenAlex

This paper presents a novel half-pel motion estimation architecture for MPEG-4 applications. The proposed architecture consists of two parts; interpolation part and full search block matching part. The first part computes the half-pel values by interpolation of the full pixels. The second part searches for the best match to the reference block using full search block matching algorithm to enhance the video quality. The proposed architecture has been prototyped, simulated and synthesized for 0.18 /spl mu/m CMOS technology using TSMC standard cells. At 50 MHz clock frequency the proposed architecture needs 120 /spl mu/sec to compute the motion vectors. The prototyped architecture consumes 247.04 mW with 1.6 V supply voltage and has core area of 0.703 mm/sup 2/.

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.
