Research Abstract

We have developed the non-contact respiration measurement system by applying the pattern light projection for realizing easy screening of Chronic Obstructive Pulmonary Disease (COPD). In this study, we apply the Self-Organizing Map (SOM) to the unforced respiratory waveform of COPD patients and healthy subjects, which are obtained by the proposed measurement. And, the automatic classification of the respiratory waveform, which is based on the difference in the waveform shape between the COPD patients and the healthy subjects, is realized.
