Mining moving patterns from object trajectories is an crucial task for understanding movement characteristics. In this study, we propose a novel trajectory analysis method to detect split-and-merge patterns based on a virtual running method. A virtual run is a rearranged moving order of objects that minimizes the cost function and is used to perform(More)
This paper proposes a new method called Virtual Run for extracting the representative trajectories from a set of similar trajectories by readjusting the sequence of movements of vehicles. This method uses convex hull and Euclidean minimum spanning tree to move the trajectory sets, so that it can generate the representative trajectories. Those representative(More)
A time series is a sequence of data sequentially observed over time. It contains important information such as stock, futures, foreign exchange rate, brainwave, heart rate, weather change, wind speed, air temperature and advective flux. Analyzing time series data is essential to estimate the future and understand scientific characteristics inherent in many(More)
