Mining Long, Sharable Patterns in Trajectories of Moving Objects
... LSPs in trajectories, it would not solve it. In comparison, the herein presented method solves the problem of mining LSPs in trajectories, which is orthogonal, but not unrelated to indexing of trajectories. In [13] a way to effectively retrieve trajectories in the presence of noise is presented. Sim ...
