Centroid TRajectory Intuitionistic FCM (CenTr_I_FCM) is a variant of the FCM clustering algorithm, which embodies CenTra at its update procedure. CenTra, tackles the problem of discovering the Centroid Trajectory of a group of movements, taking into advantage the local similarity between portions of trajectories.


CenTr_I_FCM (char * INfilename, char * OUTfilename, double density, int tau, double difference_tolerance, double epsilon, double delta_sigma, int side, int num_of_classes)

Installation Guidelines: 

The input and output file directory of the algorithm is the “c:\Hermes\IO\”
