Modeling of ECG Signal with Nonlinear Teager Energy Operator

Objective of this paper is to analyze noise free ECG signal and to discriminate the arrhythmia data from normal sinus rhythm data. ECG data is characterized by its nonlinear dynamic behavior, which shows significant changes between normal and arrhythmia data. Presence of artifacts like 60Hz power line interference (PLI), low frequency base line wander noise (2Hz) and muscle artifacts will not a...

A Robust Image Authentication Method Based on Wavelet Transform and Teager Energy Operator

A novel digital watermarking for image authentication is proposed in this paper. Most previous proposed watermarking algorithms embed sequences of random numbers as watermarks. Here images are taken as watermarks for embedding. In the proposed approach, the host image is decomposed into wavelet coefficients. Local entropies of wavelet coefficients in the low-frequency subband are calculated by ...

On the development of variable length Teager energy operator (VTEO)

Teager Energy Operator (TEO) proposed by Kaiser and Teager is based on a definition of energy required to generate the signal. TEO gives us the running estimate of energy as a function of amplitude and instantaneous frequency content of the signal. However, it considers three consecutive samples to calculate the energy estimate. In this paper, we suggests an alternative and generalized approach...

wuthering heights and the concept of marality/a sociological study of the novel

to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...

An Improved Speech Enhancement Method based on Teager Energy Operator and Perceptual Wavelet Packet Decomposition

According to the distribution characteristic of noise and clean speech signal in the frequency domain, a new speech enhancement method based on teager energy operator (TEO) and perceptual wavelet packet decomposition (PWPD) is proposed. Firstly, a modified Mask construction method is made to protect the acoustic cues at the low frequencies. Then a level-dependent parameter is introduced to furt...
