I dont have a great deal of experiance in matlab and would like some advice on detecting breathing,the samples taken in the figures attached are raw ADC inputs to matlab with no filtering , is there firstly something I could do to improve the waveforms? (pre filtering)
Also what is the best method (most reliable) to detect there is breathing and the rate of the breathing.
figures attached baseline(no one on the bed), Breathing (normal) and breathing2(shallow)
Thank you in advance for any help you can offer.
