1. A computer-implemented method for analyzing an image sequence of a periodic physiological activity, the method comprising:
receiving the image sequence acquired by an imaging device, the image sequence including a plurality of images;
identifying at least one feature portion in a selected image of the image sequence, the at least one feature portion moving responsive to the periodic physiological activity;
detecting, by a processor, the corresponding feature portions in other images of the image sequence; and
determining, by the processor, a phase of the selected image in the image sequence based on the motion of the feature portion.
