Deep Learning for Body Parts Detection using HRNet and EfficientNet
Bibliographic record
Abstract
Human body parts detection is an important field of research in computer vision. It can serve as an essential tool in surveillance systems and used to automatically detect and moderate non-appropriate online content such as nudity, child pornography, violence, etc. In this work, we introduce a novel two-step framework to define ten body parts using joints localization. A new architecture with EfficientNet as a backbone is proposed and compared to HRNet for the first step of pose estimation. The resulting joints are then used as an input to the second step, where a set of rules is applied to connect the appropriate joints and to define each body part. The developed algorithms were tested using MPII human pose benchmark. The proposed approach achieved a very interesting performance with a 90.13% Probability of Correct Keypoint (PCK) for the pose estimation and an average of 89.80% of mean Average Precision (mAP) for the body parts detection.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
