My problem is that I cannot figure the way how to generate a code that would return me the frequencies that present some peak values of the spectrum. For example, my highest vibration is somewhere near to 30 Hz,
here i have code that determine dominant frequency, but i want to find the second dominant from the signal. iftrue y = fft(x,nfft);% Fast Fourier Transform y = abs(y.^2);% raw power spectrum density y = y(1:1+nfft/2);% half-spectrum ...
'function is typically employed, and the'
The maxima of the inverse Fourier transform of this cross-power spectrum is the criteria for the detection of some acoustic events. On the video path, we define some initial color models of some desired cues such as mouth, eyes, etc. and then track them in the audiovisual scene recorded ...

Dal-Jae Yun presented a 3D scattering center extraction algorithm with a fast Fourier transform-based scheme which has been applied to tank models [15]. Though great progress has been made for the analysis of those targets with simple structures, more work should be made for analyzing objects ...
