Abstract(in English) | We propose a polarimetric remote sensing system to classify daily movements of humans such as walking and standing. We expect that anomaly in the body is detected by using electromagnetic waves and neural networks not only from biological information such as human heartbeat and respiration, but also from daily movements. The feature of this study is to acquire the Stokes vector corresponding Poincare vector as time series from the signals obtained by transmitting and receiving polarized electromagnetic wave, and to classify the human body movement with a quaternion self-organizing map (QSOM). We obtain the time-series information of polarization for various movements to analyze the changes in the polarization states in each movement. Then, we classify the human body movements adaptively by QSOM. |
