1. A method of segmenting an audio-video recording, comprising the steps of:

  • identifying one or more video frame intervals having similarity to a predetermined video image class;

    extracting one or more audio intervals corresponding to the one or more video frame intervals;

    applying an acoustic clustering method on the one or more audio intervals to produce one or more audio clusters; and

    wherein the step of identifying one or more video frame intervals comprises decimating a video portion of the audio-visual recording in time and space to produce decimated frames; and

    for each decimated frame, transforming the decimated frame to produce a transform matrix;

    extracting a feature vector from the transform matrix; and

    determining similarity of the frame using the feature vector and a video image class statistical model.
