This paper describes a method for analyzing tonality and transcribing melody stream automatically. Tonality plays the core part in organizing music structure. By making an investigation into cognition and musicology, we propose an approach to transcribe major component of polyphonic music from the point of view of tonality. Our method focuses on music cognition instead of signal processing. Basing...
This paper proposes a computing algorithm for reconstructing point-wise sources in an inverse electroencephalography problem, where only a two- dimension model for boundary problem of Poisson equation is considered. Based on the variational form of this boundary value problem, we select a special form of complex polynomial as the test function, and then derive an algebraic relationship among the source...
Different kinds of features in time domain, spectral domain and cepstral domain are used for musical genre classification. In this paper, through the fusion of short-term timbral features and long-term rhythmic feature, we propose a novel method where: musical genre vector is constructed using the likelihood ratio of GMM (Gaussian Mixture Model) and radar chart is applied to provide visualized style...
Being one of the most well-known high-level music content concepts, music key reveals an important theoretical feature for Western music in music structure analysis, music note and chord transcription and music mood comprehension. Key finding becomes a main task of music information retrieval (MIR). In this paper, we propose a novel approach with good robustness to detect keys in polyphonic music...
In this paper, the thin-film SOI substrates were used for the MOCVD growth of GaN. The in-situ stress measurement and Raman spectra were performed to characterize the stress distribution in the multi-films. The results show that the compliant SOI substrate can reduce the tensile stress in GaN epilayer by sacrificing the thin top silicon film
