Abstract
In the railway sector, track inspections are regularly needed to monitor the track conditions for potential hazards in order to ensure safety and security of life and property. Recently, conducting infrastructure inspections and monitoring using UAVs has gained attention in various industries including the railways. The rapid development of advanced deep learning and machine vision techniques have given rise to automated railway hazard detection systems based on UAV-based imagery. A major task in such systems is to localize or segment the railway tracks in UAV-based images. This paper investigates the effectiveness of a fully convolutional encoder-decoder type segmentation network called U-Net for the task of segmenting rail track regions from UAV-based images. Through experimental evaluations using a proprietary real-world dataset, we demonstrate U-Net's effectiveness in terms of mean Intersection over Union (IoU). Such methods of rail track segmentation are particularly useful in applications such as automated UAV navigation along rail tracks.

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 it
