Numerous signals arising from physiological and physical processes, in addition to being
non-stationary, are moreover a mixture of sustained oscillations and non-oscillatory …

Crowdsourcing has emerged in recent years as a potential strategy to enlist the general
public to solve a wide variety of tasks. With the advent of ubiquitous Internet access, it is now …

Full-duplex hands-free telecommunication systems employ an acoustic echo canceler (AEC)
to remove the undesired echoes that result from the coupling between a loudspeaker and a …

It has been shown in the literature that the perceptual wavelet packet decomposition
(PWPD) and the Teager energy operator (TEO) are useful for various speech processing …

Performance of wavelet thresholding methods for speech enhancement strongly depends
on estimating an exact threshold value in the wavelet sub-bands. In this paper, we propose …

This paper proposes a novel approach to registering deformations of 3D non-rigid objects
for Augmented Reality applications. Our prototype is able to handle different types of objects …

This paper presents a novel approach for blind audio watermarking. The proposed scheme
utilizes the flexibility of discrete wavelet packet transformation (DWPT) to approximate the …

Audio processing apparatus in which a payload signal is inserted into a primary audio signal
comprises a noise gen erator operable to generate a noise signal in dependence on the …

The tunable Q-factor-based wavelet transform (TQWT) is a novel method employed for the
speech enhancement (SE) task. However, in TQWT, the controlling parameters Q-factor and …

Wavelet packet transform has been progressively applied in removing the additive white
Gaussian noise. By using soft thresholding function, it performs well in enhancing the …
