Modeling of electrocardiogram signals using predefined signature and envelope vector sets
(Hindawi Publishing Corporation, 2007)
A novel method is proposed to model ECG signals by means of "predefined signature and envelope vector sets (PSEVS)." On a frame basis, an ECG signal is reconstructed by multiplying three model parameters, namely, predefined ...
Rate-distortion and complexity optimized motion estimation for H.264 video coding
(IEEE-INST Electrical Electronics Engineers Inc, 2008-02)
11.264 video coding standard supports several inter-prediction coding modes that use macroblock (MB) partitions with variable block sizes. Rate-distortion (R-D) optimal selection of both the motion vectors (MVs) and the ...
Hierarchical quantization indexing for wavelet and wavelet packet image coding
(Elsevier Science BV, 2010-02)
In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet and wavelet packet coefficients. A hierarchical classification map is defined in each wavelet subband, ...
Compression of ECG signals using variable-length classified vector sets and wavelet transforms
(Springer International Publishing AG, 2012)
In this article, an improved and more efficient algorithm for the compression of the electrocardiogram (ECG) signals is presented, which combines the processes of modeling ECG signal by variable-length classified signature ...
Adaptive Volterra channel equalisation with lattice orthogonalisation
(Institution of Engineering and Technology, 1998-04)
The authors present a new recursive least-squares adaptive nonlinear equaliser based on Volterra series expansion. The main approach is to transform the nonlinear equalisation problem into an equivalent multichannel, but ...
