    摘要： Systems and methods for compressing and sharing geotagged video in accordance with embodiments of the invention are disclosed. One embodiment includes receiving a captured video sequence, where at least one geographic location is associated with the captured video sequence, selecting a segment of the captured video sequence, identifying a set of relevant video segments from a geotagged video database based on the at least one geotag associated with the captured video sequence, determining the video segment from the set of relevant video segments that is the best match by comparing the similarity of the content in the video segments to the content of the selected segment from the captured video sequence, encoding the selected segment, where the selected segment is encoded using predictions that include references to the video segment that is the best match, and storing the encoded video segment in the geotagged video database.
