Abstract

We have examined the non-contact respiration measurement by applying the active stereo for realizing easy screening of Chronic Obstructive Pulmonary Disease (COPD). In this study, we apply the Self-Organizing Map (SOM) for classification of unforced respiratory waveform. The automatic classification of the respiratory waveform is based on the difference in the undulating pattern of respiratory waveform between the COPD patients and the healthy subjects. As the result of the experiment, it becomes clear that the classification by SOM is almost equivalent to the classification by respiratory specialists.
