Electrocardiogram analysis based on the Karhunen-Loève Transform
2010 Edition, Volume 2, October 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Karhunen-Loève Transform (KLT) is the statistically best block transform. In terms of decorrelation of the signal samples and repacking energy distributing, the signal dependent transform of KLT was used in noise eliminating, data compression...

Generalized Karhunen-Loeve transform
1998 Edition, Volume 5, June 1, 1998 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present a novel generic tool for data compression and filtering: the generalized Karhunen-Loeve (GKL) transform. The GKL transform minimizes a distance between any given reference and a transformation of some given data where the transform...

Relative Karhunen-Loeve transform
1996 Edition, Volume 44, February 1, 1996 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Karhunen-Loeve transform (KLT) provides the best approximation for a stochastic signal under the condition that its rank is fixed. It has been successfully used for data compression in communication. However, since the KLT does not consider...

The distributed Karhunen-Loeve transform
2002 Edition, January 1, 2002 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Karhunen-Loeve transform is a key element of many signal processing tasks, including classification and compression. In this paper, we consider distributed signal processing scenarios with limited communication between correlated sources, and we investigate a...

Digital Watermarking using Karhunen-Loeve transform
2007 Edition, May 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Digital watermarking is a very common technique used against illicit copying and distribution of copyright material. This paper presents improved methods for information hiding. We propose a new approach, based on the decorrelation property of the...

Extended karhunen-loève transform
2017 Edition, July 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We develop an extension of the Karhunen-Loe've transform (KLT) that provides better associated accuracy than that of the original KLT and its known generalizations. It is achieved via a special structure of the proposed transform which contains more...

Karhunen-loeve transform for sleep spindle detection
2016 Edition, March 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Automatic detection of sleep and its analysis have significant applications in clinical and driver fatigue detection. The method proposed here is aimed at detecting sleep spindles which are hallmark of beginning stage of sleep. The method uses one-dimensional EEG signal to...

The Distributed KarhunenLoève Transform
2006 Edition, Volume 52, December 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Karhunen-Loeve transform (KLT) is a key element of many signal processing and communication tasks. Many recent applications involve distributed signal processing, where it is not generally possible to apply the KLT to the entire signal; rather,...

Karhunen-Loeve transform using neural networks
1994 Edition, Volume 7, January 1, 1994 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The optimality of Karhunen-Loeve transform (KLT) over other transforms has been well known, together with the difficulty in implementing practical KLT systems. The wide applications of the transform deserve a new investigation on...

Image compression by weighted Karhunen-Loeve transform
1996 Edition, Volume 2, January 1, 1996 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We define the weighted Karhunen-Loeve transform (WKLT) and provide its general form. For use in image compression we propose a new method to reduce the blocking effects by using overlapping blocks and the WKLT. Although by decreasing the weight in...
