Abstract :
Respiratory rate sensitivity is a fundamental vital sign of different
pathological conditions. Respiration measurements can be screened to some extent.
So far, the measurement of respiratory volume has been using a spirometer through
direct contact. Where during the COVID-19 pandemic a non-contactless
measurement is needed to determine the presence or absence of respiratory
disorders. This study aims to utilize thermal imaging to extract non-contact
respiratory data in people who wear masks and without masks based on mobile
around the nostrils. Based on the results of the respiratory data obtained, normal
breathing has several characteristics including other periods of regular breathing
waves, fewer wave frequencies, a maximum deviation of about 1 degree Celsius per
wave and has a more tenuous distance along the waves. Abnormal breathing has a
regular period of breathing waves and more wave frequencies with a maximum
deviation that is higher than normal data, which is about 2 degrees Celsius in each
wave and also has short waves or density distances. Based on the results of the data
transformation into an RGB image with a total of 60 data and produces an RGB
image with a size of 60 x 60 pixels. A normal breathing image has an image pattern
with an uneven color mapping. In contrast to the abnormal breathing image, it has
a uniform color mapping pattern which is dominated by one. In both the normal
and abnormal transformed images, the false edges are opposite with different
locations
