- Abstract— In video surveillance based on motion trajectory, a moving object is considered abnormal if the distance from it to trajectory is greater than a threshold.
- If a trajectory is abnormal with sub-trajectory, it will be abnormal with entire trajectory.
- In this paper, a novel approach propose to detect abnormal based on sub-trajectory with modified Hausdorff distance.
- Moreover, the anomaly detection based on sub-trajectory that can be done with complete trajectory and incomplete trajectory.
- The result show that the technique detect abnormal with the time faster.
