1. A video compression method, comprising:
segmenting, in response to one or more features of an object in a video having a periodic change, the video into a plurality of segments based on a cycle of the periodic change;
identifying focal regions in frames of the video that are associated with the object; and
compressing the video based on the plurality of segments and the focal regions;
wherein compressing the video based on the plurality of segments and the focal regions comprises:
dividing, for a segment of the plurality of segments, frames of the segment into a plurality of frame clusters based on a similarity of the focal regions between the frames of the segment; and
compressing the segment based on the division of the plurality of frame clusters;
wherein compressing the segment based on the division of the plurality of frame clusters comprises:
determining a central frame of a frame cluster of the plurality of frame clusters, wherein the central frame is a frame in the frame cluster that is the closest to the center of the frame cluster; and
in response to a similarity of the focal regions between the central frame and another frame in the frame cluster satisfying a threshold, removing the other frame from the segment.
