Detecting patterns in waves

Question

I\'m trying to read a image from a electrocardiography and detect each one of the main waves in it (P wave, QRS complex and T wave). Now I can read the image and get a vector li

Answer 1

I haven't read each other answer thoroughly but I have scanned them and I noticed that no one recommended looking at the Fourier Transform to segment these waves.

To me it seems like a clear cut application of Harmonic analysis in mathematics. There may be several subtle points that I may be missing.

The Discrete Fourier Transform coefficients give you the amplitude and phase of the different sinusoidal components that make up your discrete time signal, which is essentially what your problem states you want to find.

I may be missing something here though ...
