ABSTRACT:
A method detects traffic events in a compressed video. Feature vectors are extracted from the compressed video. The feature vector are provided to a Gaussian mixture hidden Markov model. Then, a maximum likelihood of the Gaussian mixture hidden Markov model is determined to classify the plurality of feature vector as traffic events.
