Trajectory classification.
Input: | A GPS point ; | Output: | The activity of the person; | (1) For each | (2) Store in TW; | (3) End for each | (4) For each | (5) Classify every point in TW; | (6) Update ; | (7) Update the centers of clusters (, ); | (8) Calculate the threshold µ; | (9) //Cluster’s accumulation search | (10) If () then | (11) POI = spatial recognition (); | (12) Activity = activity discovery (POI); | (13) End if | (14) Update ; | (15) Return Activity | (16) End for each |
