Detection and Logging Advertisements using its Sound
J. G. H. Lourens · 2005
The advertisement detection system uses the energy envelope of the advertisement as signature. With a pattern-matching technique, this signature is compared to the energy envelope of the broadcasted sound. The excellent performance of the system is quantified by the false-alarm and miss rate, and by the sensitivity to time warping. Typical figures for the real-time system are quoted. >
