METHOD AND DEVICE FOR VIDEO CLASSIFICATION
Document Type and Number:
Japanese Patent JP3475317
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the method and the device in which an analysis is conducted for the sound information included in video information and the video is classified into categories without being influenced by conventional categories.
SOLUTION: A music detecting section 103 conducts a frequency analysis of the sound information of the inputted video information, detects the stability of the spectra and detects a music. A voice detecting section 104 detects the harmonic structure of the spectrum and detects voices. On the other hand, a code table generating section 105 generates a code table. Then, an acoustic detecting section 106 compares the sound information of the inputted video information with the feature vectors of the code table and the kinds of acoustics are detected by the closeness of the distance between the sound information and the feature vectors. An attribute information accumulating section 107 records the position of the segment of the detected sound information and extracts the kinds of the detected sound information, the length of each segment, the total length of every kind and the pattern of the position of each segment and a video discriminating section 108 discriminates the kind of the video information.
