There is the sample PPG data file, and there are 100 different PPG signals' data.
The sample frequency is about 30 Hz.
When I choose the 85th signal, the wavefrom is looked like this.
Obviously, the motion artifacts is between 200 sec to 500 sec.
I want to design a MATLAB code for detect whether the artfacts are and remove them.
Could anyone tell me how to do that?
I want to separate the whole waveform into different waveforms. Basicially, one waveform is for one period of PPG.
Then, to find the maximum and minimum points and calculate the difference. The parts with a great difference shall be the artifacts.
Could anyone tell how to do that via MATLAB code?
