Pitched Instrument Onset Detection based on Auditory Spectra
In this paper, a novel method for onset detection of music signals using auditory spectra is proposed. The auditory spectrogram provides a time-frequency representation that employs a sound processing model resembling the human auditory system. Recent work on onset detection employs DFT-based features, such as the spectral flux and group delay function. The spectral flux and group delay are int...
متن کاملDetection of therapeutic radiation in three-dimensions
For over the last twenty years there has been a multitude of sophisticated three-dimensional radiation delivery procedures developed which requires a corresponding verification of the impact on patients. This article reviews the state of the art in the development of chemical detectors used to characterize the three-dimensional shape of therapeutic radiation. These detectors are composed of pol...
متن کاملRadon Transform Based Instrument Shaft Detection in Three-Dimensional Ultrasound
Real-time three-dimensional ultrasound enables new intra-cardiac surgical procedures, but the distorted appearance of instruments in ultrasound poses a challenge to surgeons. This paper presents a detection technique that identifies the position of the instrument within the ultrasound volume. The algorithm uses a modified Radon transform to search for long straight objects in the ultrasound ima...
متن کاملThe importance of the non-harmonic residual for automatic musical instrument recognition of pitched instruments
In different papers dealing with automatic musical instrument recognition of pitched instruments, the features used for classification are based solely on the fundamental frequencies and the harmonic series, ignoring the nonharmonic residual. In this paper we explore whether instrument recognition rate of pitched instruments is decreased by removing the non-harmonic information present in the s...
متن کاملMusical Offset Detection of Pitched Instruments: The Case of Violin
Musical offset detection is an integral part of a music signal processing system that requires complete characterization of note events. However, unlike onset detection, offset detection has seldom been the subject of an in-depth study in the music information retrieval community, possibly because of the ambiguity involved in the determination of offset times in music. This paper presents a pre...
