feet, which can facilitate for them how to deal
with such a medical case. The new mobile
thermal camera FLIR ONE was used for this
purpose along with an application that was
developed to identify possible ulcers. The
mobile application, in its first form, was tested
successfully under simulated conditions,
which included heating 4 different areas in
the feet to check the ability of the proposed
application to identify certain elevated
temperature regions. One image was tested for a temperature difference less than 2.2
degrees Celcius and the other three images
were tested with temperature increased
slightly greater than 2.2 degrees Celcius. The
system has successfully identified the hottest
region and if it represents a possible ulcer
or not. It is worth to keep in mind that this
application is not a diagnosis tool; instead, it
is just an indicator for DFU’s. The patient must
immediately consult his/her physician for a
complete checkup. Early prevention techniques
