Thermal Fall 66: A robust dataset for thermal imaging-based fall detection and eldercare
Bibliographic record
Abstract
Fall-related injuries pose a significant health risk, particularly among the elderly population, necessitating advancements in fall detection technologies. While traditional sensor-based methods offer some solutions, they are limited by issues, like user compliance and unreliability in high-stakes situations. Computer vision (CV) and artificial intelligence (AI)-based alternatives, notably thermal imaging, emerge as promising, privacy-preserving tools. However, the lack of standardized, generalizable benchmark datasets hampers the validation of these technologies’ effectiveness. The Thermal Fall 66 (TF-66) dataset introduced in this work addresses this crucial gap by providing an extensive, diverse collection of fall scenarios, recorded in various environments and featuring a wide range of participants. This dataset introduces sample subsets for tailored model training and a comprehensive data generator for customized access, setting a new benchmark in fall detection research. A baseline three-dimensional convolutional neural network (3D CNN) was trained to demonstrate the dataset’s suitability for supervised deep learning. As TF-66 continues to evolve, it aims to include even more diverse environments, such as bathrooms and staircases, further enhancing its applicability and serving as a robust resource for the research community. This work contributes significantly to the field by offering a dataset that not only improves the reliability of fall detection systems (FDS) but also facilitates a standardized approach to evaluating and advancing these technologies.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
