Trajectory anomaly detection.
| Input: | | normal trajectory model | | trajectory | | Output: | | abnormal index | | Begin: | (1) | trajectory feature extraction | (2) | update normal trajectory model by Incremental DBSCAN | (3) | for each do | (4) | calculate trajectory distance | (5) | get the minimum trajectory difference | (6) | return | | End |
