I'm using spectrogram to plot time vs frequency representation of STFT signal? Basically How to detect peaks in spectrogram?

The findpeaks function will not work with spectrogram, since it only works with vectors. You have to threshold the absolute value of the spectrogram function. See this thread for an example.

Looks like you'll have to use image analysis. Threshold the image. Might be beneficial to do some noise reduction first.
