Recognition of Music Scores with Non-Linear Distortions in Mobile Devices
Multimedia Tools and Applications, 2017Optical music recognition (OMR), when the input music score is captured by a handheld or a mobile phone camera, suffers from severe degradation in the image quality and distortions caused by non-planar document curvature and perspective projection.

OPTIMAL EVALUATION OF WAVEFORM DISTORTION INDICES WITH PRONY AND ROOT MUSIC METHODS
International Journal of Power and Energy Systems, 2007Representation of signals in time and frequency domain has been of interest in power systems for many years, especially in the case of nonstationary signals. Standard tools of waveform distortion analysis are based on the Fourier transform while only recently the Prony and rootMusic methods were tested for this purpose.

On peculiarities of evaluating the quality of speech and music signals subjected to phase distortion
2017 IEEE 37th International Conference on Electronics and Nanotechnology (ELNANO), 2017In this paper, subjective and objective estimators of the quality of speech and music signals subjected to phase distortion are compared, and mapping between objective and subjective quality estimates is realized. It was found that the phase distortion of speech signals is perceived stronger than ones for musical signals.

A Robust Detector for Distorted Music Staves
2005In this paper an algorithm for music staves detection is presented. The algorithm bases on horizontal projections in local windows of a score image and farther processing of resulting histograms and their connections. Experiments carried out, proved high efficiency of presented algorithm and its robustness in case of non-ideal staff lines: skew and ...

Electroacoustic distortions: Multidimensional analysis of hearing aid transduced speech and music
ICASSP '78. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005The detrimental effects of electroacoustic distortions on quality judgement of speech and music was investigated using a posteriori techniques of multidimensional scaling. Evaluative data consisted of preference and similarity judgments from pairwise presentation of 12 hearing aids to normal listeners.

A study on a digital watermarking technique for music data using distortion effect
2017 Eighth International Workshop on Signal Design and Its Applications in Communications (IWSDA), 2017In this paper, we propose a novel concept of a digital watermark for music data that focuses on the use of sound effect techniques. This paper describes our proposed technique, which utilizes the distortion effect, frequently employed especially for guitar and bass instruments.

Some Results Concerning the Perception of Musical Distortion in Mistuned Single Sideband Links
IEEE Transactions on Communications, 1975Tests were performed over a good communications grade single sideband (SSB) channel on the listenability of various types of music under frequency shift distortion up to ± 30 Hz. Sensitivity to this type of distortion depends upon the type of music, and frequency shift should be less than ± 5 Hz to avoid noticeable degradation.

A novel W-MUSIC algorithm for GPR target detection in noisy and distorted signals
2009 IEEE Radar Conference, 2009When applied to ground penetrating radar (GPR), the multiple signal classification (MUSIC) algorithm is an important frequency estimation method as it can detect very closely spaced targets, particularly when one of the target responses is substantially less than another. The MUSIC algorithm however must be seeded with the number of targets to find and

The goals of this study were to characterize and model the perception of nonlinearly distorted speech and music by hearing-impaired listeners. Hearing-impaired listeners were asked to rate the perceived quality of speech and music that had been subjected to various forms of nonlinear distortion, some of which are inherent to certain hearing aid designs
