... the specificity of the obstructive sleep apnea detector is evident. The TFR-based parameter estimation is a remarkable fac- tor for an adequate dynamic feature generation. Therefore, for OSA detection, ... as well. Therefore, photoplethysmography-based detection provides an adequate scheme for obstructive sleep apnea diagnosis. 1. Introduction Regarding the diagnosis of...

... each detector of the sensor senses a pixel of size equal to the GSD. For a line of detectors, the values received at these detectors correspond to the sampling of a continuous signal corresponding to the ... representing the evolution of the probability of detection with respect to the probability of false alarms. So far, these curves are computed using results of d...

In addition, when the headset microphone moves away from the position of the mouth, users need to be able to adjust the position of the headset microphone by themselves. ... can execute these functions in real time on the CPU board. The sampling rate of the A/D converter is set to 8 kHz due to the limitation of the processing capac...
