Claim 1:
2. The method of claim 1, wherein the motion cycles are respiratory cycles, and a respiratory cycle includes a duration between adjacent peaks or a duration between adjacent valleys, and a half respiratory cycle includes a duration between a peak and a corresponding valley,, wherein determining durations of actual motion cycles based on durations of the plurality of motion cycles comprises:
determining a distribution of the motion cycles, the distribution of the motion cycles indicates a probability that each motion cycle of the plurality of motion cycles corresponds to an actual motion cycle;
determining durations of actual motion cycles based on the distribution of the motion cycles,
wherein determining a distribution of the motion cycles comprises:
determining a plurality of respiratory cycles based on the respiratory signal;
determining a first distribution of the respiratory cycles based on the plurality of respiratory cycles, wherein the first distribution includes at least one of an average respiratory cycle, a variance of the respiratory cycles, or a skewness of the first distribution; or
determining a plurality of half respiratory cycles based on the respiratory signal; and
determining a second distribution of the half respiratory cycles based on the plurality of half respiratory cycles, wherein the second distribution includes at least one of an average half respiratory cycle, a variance of the half respiratory cycles, or a skewness of the second distribution.
