Movie 1.

A vocalizing focal meerkat. Synchronized sample of thermal video and audio recording. starting from 00:46 sec – A series of manual pings used for synchronization, slowed down to 33% of original playback speed. starting from 01:16 – A sample of tracked nostril ROI video as outputted by Loopy pose estimation tool (loopbio gmbh, Austria). Green dot marks detections of left nostril centre. Red dot marks detections of right nostril centre. Starting from 02:00 – Sample thermal video sequence demonstrating the nasal ROI used for estimating respiration trace from changes in surface temperature. Real time temperature plot is showing the median temperature reading of the left nostril. The cyclic pattern of the temperature curve is typical to respiration. The insert shows magnified nasal area, at a slowed down playback speed, emphasizing the changes in the nostril intensity.
