-Abstract
Respiration rate is an important indicator of an individual’s health. It is the average number of times air
is inhaled and exhaled per minute. A real-time thermal imaging based respiration rate monitoring method used to find
the rate of respiration. It is not only measuring the respiration rate at the temperature changes under the tip of the nose
it is also measures the respiration related to skin surface temperature. Facial tracking was used to monitor the motion of
the head. The Robust algorithm used to remotely monitor breathing rate by using thermal imaging. The tip of the nose is
detected and then, a region just under it was selected and detected inner corner of the eyes. A region of interest was
created under the tip of the nose and the pixel values within it were averaged to produce a single feature for each image.
The pixel values in this region between successive images were processed to determine respiration rate. The filtered
signal was widowed with the Kaiser window and its magnitude, frequency spectrum was obtained. With the range of
frequencies obtained the type of diseases are detected.
