Abstract

fetched live from OpenAlex

This paper presents a novel quarter pel full search block motion estimation architecture for H.264/AVC encoder. The proposed architecture is capable of calculating all 41 motion vectors required by the various size blocks, supported by H.264/AVC, in parallel. The architecture has been prototyped in Verilog HDL, simulated and synthesized for Xilinx Virtex2 FPGA. The experimental result shows that the architecture is capable of processing CIF frame sequences in real time considering 5 reference frames within the search range of -3.75 to +4.00 at a clock speed of 120 MHz. The maximum speed of the architecture is around 150 MHz.

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.
