This papers examines the use of trajectory distance measures and clustering techniques to define normal and abnormal trajectories in the context of pedestrian tracking in public spaces. In order to detect abnormal trajectories, what is meant by a normal trajectory in a given scene is firstly defined. Then every trajectory that deviates from this normality is classified as abnormal. By combining Dynamic Time Warping and a modified K-Means algorithms for arbitrary-length data series, we have developed an algorithm for trajectory clustering and abnormality detection. The final system performs with an overall accuracy of 83% and 75% when tested in two different standard datasets.
