Advanced Infrared Face Mask Segmentation Using a Custom Lightweight U-Net Model
Bibliographic record
Abstract
Face mask segmentation in the infrared domain rep-resents an innovative technique aimed at improving the accuracy and efficiency of detecting and isolating face masks in thermal images. This approach holds significant relevance in various applications, such as enhancing public health by verifying mask usage in medical environments, improving security through more accurate facial recognition of individuals wearing masks, and advancing human-computer interaction by enabling hands-free device control in mask-mandatory settings, thereby promoting safety and hygiene. In this research, we propose a novel solution that employs deep learning algorithms with infrared imaging to overcome the limitations of conventional mask detection methods. The core of this solution is a custom-designed, optimized variant of the U-Net model. Furthermore, this study forms part of a larger project focused on developing stations for detecting and quantifying leaks in medical masks across various mask types using infrared technologies and artificial intelligence.

How this classification was reachedexpand
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.
