Abstract

<P>PROBLEM TO BE SOLVED: To provide a scene classifier capable of enhancing precision of section detection. <P>SOLUTION: This scene classifier is provided with a time peak detecting part 5 for detecting a time peak in a spectrogram, and a frequency directional feature amount extracting part 6 for extracting a feature amount indicated in the time leak, and uses also the feature amount concerned in the time peak, as an index for the section detection. The scene classifier is provided further with a mutual feature amount extracting part 7, and classifies scenes, using also a new feature amount defined by an interaction between a frequency peak and the time peak, as an index. <P>COPYRIGHT: (C)2009,JPO&amp;INPIT
