Abstract

fetched live from OpenAlex

We proposed an algorithm of acquiring and tracking human body skeleton from 3D voxel data. We got the voxel data via 16 cameras. Voxel defines the information of the points in 3D space, including each point in X, Y and Z coordinates. It is a hot and difficult topic in the field of computer vision for us to get accurate and real -time human body skeleton information from voxel data. By using the Quantum-inspired Evolutionary Algorithm (QEA) for reference, it is an effective method to apply the ideas of iteration and optimization into skeleton extracting. The experiment results show that the algorithm is effective and robust in skeleton extracting and tracking.

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.
