In this paper, we propose SakuraSensor, a participatory sensing system which automatically extracts scenic routes information from videos recorded by car-mounted smart-phones and shares the information among users in quasirealtime. As scenic routes information, we target flowering cherries along roads since the best period of flowering cherries is rather(More)
<i>SakuraSensor</i> is a participatory sensing system for collecting short videos of cherry-lined roads by in-vehicle smartphones to provide scenery-based route recommendation services for comfortable driving. To detect good cherry-lined roads and record their videos automatically during driving, image analysis techniques are performed on user's smartphone,(More)
In this paper, we proposed a method to estimate the destination of walking persons from their walking patterns, for avoidance of collision accidents between pedestrians and robots in a human-robot coexistence environment. We adopted the hidden Markov model (HMM) as a model to represent walking patterns. We constructed a model for each movement pattern. A(More)
