MATLAB: How to convert 2D ECG image to 1D ECG signal

ecg watermarking

How do I convert the 2D watermarked image to 1D watermarked ECG signal before transmitting it.

Best Answer

Hi,

Pan Tompkins algorithm is commonly used to detect QRS complexes in ECG signals through various filtering processes. There is no straight forward way to get back the ECG signal from an Image (may look over some papers that do so using Deep learning algo). For more insights upon Watermarking kindly go through the following link

Thanks

As long as sig is 1D, you should be getting 1D output.

    >> sig=1:5;  %1D signal
    >> abs(ifftshift(ifft(sig))) %1D output
    ans =
        0.5257    0.5257    0.8507    3.0000    0.8507

doc fft %the documentation example is very good

Good filtering example

ECG generator

Very simple example how to add noise to a wave:

t=0:0.1:10; %from 0 to 10 seconds, sampling 0.1 seconds
y=sin(t); %measured amplitude
n=0.1*rand(1,numel(t)); %noise to add
plot(x,y+n)
