Abstract

This paper unveils a thermal imaging methodology to recover the breathing waveform from the subject's nostrils. The resulting functionality is equivalent to that of a thermistor, but it is materialized in a contact-free manner. First, the nostril region is segmented and tracked over time through a network of cooperating probabilistic trackers. The mean thermal signal of the nostril region carries the breathing information. This information is extracted through wavelet analysis. The method has been tested on 20 healthy individuals. The breathing waveforms determined via the imaging computation were compared with the corresponding ones extracted from thermistors. The high degree of agreement between the two measurement methods confirms the validity of the proposed approach and opens the way for clinical applications. Furthermore, thermal imaging can be potentially used as an investigative tool to understand breathing physiology in ways not possible with contact sensors.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
