Claim 23:
24. The apparatus of claim 23, further comprising:
computing at least one local characteristic of the IQ in the time window when the object has a stable rhythmic motion, wherein the at least one local characteristic comprises at least one of: a local maximum, local minimum, zero crossing, local maximum of a derivation of the IQ, local minimum of the derivative, and zero crossing of the derivative;
segmenting the time window into at least one step segment based on time stamps associated with the at least one local characteristic of the IQ, each step segment spanning from a time associated with a local characteristic to another time associated with a next local characteristic; and
identifying at least one motion cycle, each motion cycle comprising N consecutive step segments, wherein N is a positive integer.
