Outline of Final Research Achievements

In this research, we studied on noncontact and simultaneous measurement of human breathing for multiple users, by using far infrared (FIR) imaging. We first proposed methods to extract the regions including nasal cavity or oral cavity from FIR images which was capturing a single user's face. We next proposed methods to estimate qualitative strength of flow velocity in nasal breathing and oral breathing. Finally, we showed that noncontact and simultaneous measurement of human breathing for multiple users can be realized by using the above two methods.
