摘要

Given a trajectory we study the problem of reporting all subtrajectory clusters of . To measure similarity between trajectory we choose the Fréchet distance. We adapt an existing serial algorithm into a GPU parallel algorithm, resulting in substantial speed-ups, in some cases up to x faster, and increasing the size of the data that can be handled in reasonable amount of time, tests were performed on trajectories three times the size as previously managed. This is to the best of our knowledge not only the first GPU implementation of a subtrajectory clustering algorithm but also the first implementation using the continuous Fréchet distance, instead of the discrete Fréchet distance.
