1. A method of tracking an object, the method comprising:
- receiving a video;
encoding the video to generate an encoded video;
extracting a motion vector from the encoded video;
generating object movement information on an object on the basis of the motion vector; and
tracking a temporal movement pattern of the object on the basis of the object movement information.
