Abstract

Advertisement detection in a TV video recording/archiving system is a challenging task. In this paper, shot change (hard cut) detection that is based on 'inter-frame difference', 'normalized difference energy' and the 'normalized sum of absolute differences' and its comparison with a threshold are discussed. The effects of changing video threshold on hard cut detection have been summarized. A threshold value is evaluated for the efficient extraction of complete advertisement. Effects of various thresholds are extensively tested on more than 20 hrs of TV video streams. The frequency of shot breaks along with blank frames is considered as a key component in advertisement detection. Results of these MATLAB and LabVIEW based computer simulations have been reported.
