极大极小值原理产生阈值对人体胸壁微动信号的“WaveShrink”降噪

Application of waveShrink denoising with threshold generated by minimax estimation to analyses of oscillations in chest wall

人体胸壁微动信号中包含大量的生命体征信息。本文采用极大极小值原理产生阈值,应用“WaveShrink”算法从胸壁微动信号中提取心动信号,以量化的形式揭开胸壁振动的奥秘。

The oscillations in chest wall consist many life characteristics.In this paper,WaveShrink denoising with threshold generated by minimax estimation is employed to pick up the signal of heartbeat.The secret of the oscillations in chest wall is exploited scalably.
