I am studying windowed Fourier ridges for my project. I know that it computes the instantaneous frequencies and amplitudes from the spectrogram. But I don't really know how it relates to signal processing, can anyone explain this concept to me?

$\begingroup$ What exactly about Image restoration using the DFT don't you understand? Is there an algorithmic problem, or an issue you face? For example, why do you need the instantaneous frequencies/amplitudes from the spectrogram? $\endgroup$– Tom KealySep 13, 2013 at 9:40
