This is a Python implementation of Coherent Moving Cluster algorithm. The origin algorithm is implemented By @ws-choi in Java. Run Test_Driver.py for testing. Inputs: 1- A set of trajectories 2- An integer m 3- A lifetime k 4- A distance threshold e Output: Set of groups of objects travelling together with respect to parameters m and e for at least k consectutive timestamps Data (csv file) is provided in Ressource folder: obj_id:object id t: timestamp x: x-coordinate of the object y: y-coordinate of the objcet
