Research On Music Emotion Recognition Model And Interactive Technology

There are homogeneity and isomorphism between music and emotion of human being, and emotion is the essence of music. Research on music's affective computing model plays an important role in digital entertainment and harmonious human-machine interactive, and belongs to the field of artificial emotion, which can improve the affective interactive ability of products in digital entertainment and enrich the content of human-machine interactive.Theoretically, this thesis attempt to construct an architecture of music's affective computing, which includes such aspects as digital denotation and linguistic computing model, music emotion recognition, music retrieval based on affective semanteme, and emotion-driven algorithm composition. Technically, it can construct an effective engine for automatically incidental music for character animation constrained by some affective request, which can be used for animation, game, new media and intangible cultural heritage protection engineering.This thesis is an intersection study of computer application, music aesthetics, artificial intelligence and cognitive psychology. The following works have been researched on music's affective computing model, music emotion recognition, and music emotion expression. We have six primary part of contributes as follows:The 2^nd chapter: On the fundamental of music aesthetics and music psychics, a novel music affective model of linguistic computing is proposed. Based on semantic similarity relation among linguistic labels, this thesis models on music emotion and establishes the syntax and reasoning rules of music affective linguistic labels system. And lastly, according to a semantic recognition experiment, we construct the music affective space based on basic linguistic labels set and fuzzy relation matrix.The 3^rd chapter: Aimed at MIDI files whose characters are easy parsed, a series of features recognition algorithms are proposed: key melody track based on interval statistical comparison and improved BP, key melody extraction algorithm employed...
