In addition to the large amount of available open-source GIS software, various types of data (e.g., boundary data for administrative regions, numerical data for individual...
We propose a video search system with a three-level hierarchy model for searching videos from works, scenes, and shots. Videos are useful research materials; however, their scholarly use is very limited because finding the desired information is a time-consuming task for scholars. To provide solutions to this problem, we developed a system with fun...
We propose a video data management system built on a hierarchical structure, in which each video is a work that is divided into scenes, and the scenes are further subdivided into shots to improve search efficiency. In our system, scene-level video segmentations are manually defined according to scene transitions. However, shot-level video segmentat...
