Probabilistic spatial filter estimation for signal enhancement in multi-channel automatic speech recognition Kayser, Hendrik; Moritz, Niko; Anemüller, Jörn: Conference Paper: Retrieval of textual song lyrics from sung inputs Kruspe, Anna M. Conference Paper: A review on conventional psychoacoustic evaluation tools, methods and. The method was almost free of artifacts and does not require any manual parameter tweaking. Recently, dynamic range compression based on two-scale decomposition has been proposed. The base layer was obtained using a nonlinear BLT filter and detail layer was computed by taking difference between the input image and the base layer. Only the Cited by: 9.
The core of our method is a two-stage single-channel speech enhancement scheme. Degraded speech obtains a sparser representation of the linear prediction residual in the first stage of our proposed scheme by applying orthogonal matching pursuit on overcomplete bases, trained by the K-SVD algorithm. The other method is to use a second set of coils for only backward signal transmission. The advantage for the second method is the ability to perform forward and backward transmission simultaneously and independently, but the disadvantage is the increased size due to the second set of coils and additional by:

[D P Garber; Langley Research Center.]. A method for evaluation of parasitic frequency modulation (wow) in archival audio is presented.
The proposed approach utilizes sinusoidal components tracking as their variations correspond with the wow defect. The sinusoidal modeling procedures are used to extract the tonal components from severely distorted and significantly modulated audio Cited by: 1.

This paper describes a new speech enhancement approach using perceptually based noise reduction. The proposed approach is based on the application of two perceptual filtering models to noisy speech signals: the gammatone and the gammachirp filter banks with nonlinear resolution according to the equivalent rectangular bandwidth (ERB) scale.
The perceptual filtering gives a number of subbands Cited by: 4. USA1 US11/, USA USA1 US A1 US A1 US A1 US A US A US A US A1 US ACited by: A), reported in Y. Ephraim, “A Bayesian estimation approach for speech enhancement using hidden Markov models”, IEEE Trans.

FD evaluation have some drawbacks that this method does not cover all possible ranges for textiles, that is, any value from totherefore it is not applicable to many types of textiles.

The problem of restoring noisy-blurred images is important for many medical image applications, especially in confocal microscopy [92,] 92 The goal of image restoration is to “undo” the blurring and noise artifacts.
