Abstract

fetched live from OpenAlex

This paper presents a new hardware architecture for pattern detection and classification specific for human face detection including raw image acquisition, integral image creation, window extraction, pyramid generation, and detection algorithms in simultaneous steps. The detection part of the face is implemented in a reconfigurable way by providing different paths for either Viola-Jones or block LBP algorithms. The Adaboost algorithm using Haar features are calculated in parallel being implemented in hardware. The reconfigurability of the hardware relates to the implementation of high level commands which can switch between different algorithms for face detection as well as between various paths used for image acquisition. As such, the architecture can be used by either still or video-based face detection which very important for face tracking. The performance of the architecture depends very much of the FPGA device used. An implementation on Xilinx Spartan 6, ZYNQ, and Xilinx Virtex-7 has been accomplished. The performances of the two implementations are compared in the end of this paper.

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.
