In particular, we adopt the dynamic texture
model, an auto-regressive stochastic process, which encodes the
appearance and the underlying motion separately into two
probability distributions. With this representation, retrieval of
similar video sequences and classification of traffic congestion
can be performed using the Kullback-Leibler divergence and
the Martin distance. Experimental results show good retrieval
and classification performance, with robustness to environmental
conditions such as variable lighting and shadows.
