Application of Artificial Intelligence in an Unsupervised Algorithm for Trajectory Segmentation Based on Multiple Motion Features

Algorithm 2

Trajectory merging method.

Input: The raw trajectory , Segment point sequence

Output: The set of sub-trajectories

1:  Segment the raw trajectory by

2:  The number of sub-trajectories

3: 

4:   The and its next sub-trajectory

4:   Mergers and into

5:   Calculate the value of the loss function of , and

6:  

7:   merges and from the local perspective

8:  end if

9: end for

10:  The set of sub-trajectories
