Abstract
Described are various technologies pertaining to identifying a dominant frequency in an acquired signal, such as a frequency corresponding to a human heartbeat in an acquired video signal. In connection with identifying the dominant frequency, a sub-signal of the acquired signal is extracted from the acquired signal, where the sub-signal includes Nnumber of samples (frames). A looped signal is generated by looping the sub-signal. Nis incremented, and the process is repeated until Nis equivalent to a predefined threshold; accordingly, numerous looped signals are formed. The dominant frequency is identified based upon the looped signal and presented with the corresponding uncertainty based on harmonic analysis.
