They can also provide us some tips for creating new ideas. However, reviewing the meeting video efficiently is difficult because we can not identify whether the video includes the target scenes until we open and play it. In this paper, we propose a review supporting system for meeting videos based on notes timeline. In this system, each highlighted note on a whiteboard is extracted and clipped out as a still image with its time stamp from the meeting video. Those images are sorted by the time stump, and are arranged along the seek bar. We can easily grasp when and what was discussed in the meeting videos from the sequence of those images. They can be used as the playing indexes of the videos. Experimental results showed that the precision and recall value of note-block extraction were 87% and 77%.}, title = {書き込みの時間軸表示によるホワイトボードログの振り返り支援システムの実装}, year = {2012} }
