Audio source separation is a useful preprocessing step for remixing or transcription of music. It can be shown, that the separation quality increases, if the separation algorithm gets additional side information, e.g. the score of the current mixture [5]. In many cases the score of a musical piece is not available and has to be extracted by a professional musician or an automatic music transcri...

Hyperspectral data is modeled as an unknown mixture of original features (such as the materials present in the scene). The goal is to find the unmixing matrix and to perform the inversion in order to recover them. Unlike first and second order techniques (such as PCA), higher order statistics (HOS) methods assume the data has nongaussian behavior are able to represent much subtle differences am...

Several notions on soft topology are studied and their basic properties investigated by using the concept of pre open sets closure operator which derived from basics set theory established Molodtsov [1]. In this paper we introduce some separation axioms called Soft R0 R1 in topological spaces defined over an initial universe with a fixed parameters. Many characterizations these have been demons...

In a variety of applications of audio signal processing, for example blind source separation (BSS), harmonic signals need to be treated differently from percussive signals. Thus, recognizing if a signal is harmonic or percussive is a very helpful and frequently used preprocessing step. Different measures have been proposed to capture either the harmonicity or the percussivity of a signal, using...

Successful speech enhancement by convolutive blind source separation (BSS) techniques requires careful design of all aspects of the chosen separation method. The conventional strategy for system initialization in both timeand frequency-domain BSS involves a diagonal center-spike FIR filter matrix and no data preprocessing; however, this strategy may not be the best for any chosen separation alg...
