GeoTree: Using spatial information for georeferenced video search

作者：

Highlights：

• A new indexing method, called GeoTree, is proposed to support an efficient search of georeferened videos.

• Georeferenced videos are the videos with location and direction information captured by smartphones or vehicle blackboxes.

• GeoTree is faster and more efficient than R-tree for searching georeferenced videos.

• An online demo is available at ”http://dm.postech.ac.kr/geosearch”.
