摘要:
A method and apparatus for classifying mood of music at high speed. The method includes: extracting a Modified Discrete Cosine Transformation-based timbre feature from a compressed domain of a music file; extracting a Modified Discrete Cosine Transformation-based tempo feature from the compressed domain of the music file; and classifying the mood of the music file based on the extracted timbre feature and the extracted tempo feature.

Embodiments of the present invention relate to a method, medium, and system for summarizing music. The method includes summarizing a music content by extracting an audio feature value from a compressed segment of music data, tracking change points of the music content using the extracted audio feature value and re-configuring segments, selecting a fixed length fragment from each of the reconfigured segments and clustering the selected fragment so as to measure similarity and redundancy between the respective segments, and generating a summary of the music content using a segment selected based on the measured similarity and redundancy between the respective segments.

Disclosed herein is a process for preparing an antimicrobial elastic fiber. The process comprises: mixing a glass compound, as an antimicrobial agent, containing ZnO, SiO2, and an alkali metal oxide, and having an average particle size of 0.1 μm to 5 μm, with a dispersant; sand grinding or milling the mixture; and adding the ground or milled mixture to a solution of a segmented polyurethane polymer to prepare an elastic yarn. The process can provide advantageous effects that spinnability is improved and the color of yarn remains unchanged.
