摘要

Animated picture is classified making use of the audio signal. Acquiring the audio signal, it extracts the section feature which is the feature which relates to the frequency distribution of sound plural sections of the predetermined time length which the audio signal which you acquire includes concerning respectively, comparing with section feature and standard section feature each one which are extracted, it calculates section similarity it shows the correlation with the section feature and standard section feature. It extracts the comprehensive feature which is the feature which is based on plural section similarity it was calculated concerning the audio signal which you acquire, plural sections in respectively relates to plural sections, comparing with comprehensive feature and the standard comprehensive feature which are extracted, it classifies that audio signal of as a result on the basis. And, the taxonomic result is used for the classification of animated picture.
