Abstract

One of the more important issues in intelligent video surveillance systems is the ability to handle events from the motion of objects. Thus, the classification of the trajectory of an object of interest in a scene can give important information to higher levels of recognition. In this context, it is crucial to know what trajectories are commonly given in a model in order to detect suspect ones. This implies the study of a set of trajectories and grouping them into different categories. In this paper, we propose to adapt a bioinspired clustering algorithm, growing neural gas, that has been tested in other fields with high level of success due to its nice properties of being unnecessary to know a priori the number of clusters, robustness and that it can be adapted to different distributions. Due to the fact that human perception is based on atomic events, a segmentation of the trajectories is proposed. Finally, the obtained prototype sub-trajectories are grouped according to the sequence of the observed data to feed the model.
