Calculation of Leakage in Water Supply Network Based on Blind Source Separation Theory
The economic and environmental losses due to serious leakage in the urban water supply network have increased the effort to control the water leakage. However, current methods for leakage estimation are inaccurate leading to the development of ineffective leakage controls. Therefore, this study proposes a method based on the blind source separation theory (BSS) to calculate the leakage of water...
متن کاملMultistage convolutive blind source separation for speech mixture
Blind source separation for convolutive mixture of speech signals has been addressed in many literatures. However, widely applied Multichannel Blind Deconvolution (MBD) method suffers whitening effect or arbitrary filtering problem which results in dramatic decrease of Automatic Speech Recognition system’s performance. In present paper, a new MBD based multistage method is proposed, in which co...
متن کاملSpectral Analysis of Speech: A New Technique
ICA which is generally used for blind source separation problem has been tested for feature extraction in Speech recognition system to replace the phoneme based approach of MFCC. Applying the Cepstral coefficients generated to ICA as preprocessing has developed a new signal processing approach. This gives much better results against MFCC and ICA separately, both for word and speaker recognition...
متن کاملReal-Time Prototype for Integration of Blind Source Extraction and Robust Automatic Speech Recognition
This demo presents a real-time prototype for automatic blind source extraction and speech recognition in presence of multiple interfering noise sources. Binaural recorded mixtures are processed by a combined Blind/Semi-Blind Source Separation algorithm in order to obtain an estimation of the target signal. The recovered target signal is segmented and used as input to a real-time automatic speec...
متن کاملA comparison of simultaneous 3-channel blind source separation to selective separation on channel pairs using 2-channel BSS
A number of real-life speech applications using BSS have been reported for two channel applications but only a few have been reported for multi-channel (more than 2 channels) applications. Moreover these mostly involve simulation studies or real-life separations in controlled settings. In this paper some practical problems of multichannel applications will be analyzed. A methodology is proposed...
