Boosting Clusters of Samples for Sequence Matching in Camera Networks

This study introduces a novel classification algorithm for learning and matching sequences in view independent object tracking. The proposed learning method uses adaptive boosting and classification trees on a wide collection (shape, pose, color, texture, etc.) of image features that constitute a model for tracked objects. The temporal dimension is taken into account by using k-mean clusters of sequence samples. Most of the utilized object descriptors have a temporal quality also. We argue that with a proper boosting approach and decent number of reasonably descriptive image features it is feasible to do view-independent sequence matching in sparse camera networks. The experiments on real-life surveillance data support this statement.
