چکیده

A high-performance Karhunen-Loève transform for multi-spectral imagery suitable for remote-sensing applications has been prototyped on a platform FPGA, by means of a PC-based development board. Performance estimates suggest that the design will already outperform implementation on a high-end microprocessor, given due attention to I/O (Input/Output). General conclusions are reached for the utility of this architecture for fine-grained parallel processing, when the design is extended to massively parallel processing.

Development of a fine-grained parallel Karhunen Loève transform

A high-performance Karhunen-Loève transform for multi-spectral imagery suitable for remote sensing applications has been prototyped on a platform FPGA, through hardware compilation onto a PC-based development board. Performance estimates suggest that the design will outperform implementation on a high-end microprocessor, given due attention to I/O (Input/Output). Detailed analysis of the design...

Feature Extraction and Shape Representation of Ambulatory Electrocardiogram Using the Karhunen-Loève Transform

We developed a new approach to feature extraction and shape representation of QRS complex and ST segment pattern vectors of ambulatory electrocardiograms using the Karhunen-Loève transform. We describe applying the Karhune-Loève transform to the ambulatory electrocardiogram, derivation of robust covariance matrices using kernel-approximation method and with noisy patterns excluded, a method to ...

Sparse time-frequency representation of speech by the vandermonde transform

Efficient speech signal representations are prerequisite for efficient speech processing algorithms. The Vandermonde transform is a recently introduced time-frequency transform which provides a sparse and uncorrelated speech signal representation. In contrast, the Fourier transform only decorrelates the signal approximately. To achieve complete decorrelation, the Vandermonde transform is signal...

Approximation of the Karhunen-Loève transformation and its application to colour images

Analysis of colour images in the Red, Green and Blue acquisition space and in the intensity and chrominance spaces shows that colour components are closely correlated (Carron, Ph.D. Thesis, Univ. Savoie, France, 1995; Ocadis, Ph.D. Thesis, Univ. Grenoble, France, 1985). These have to be decorrelated so that each component of the colour image can be studied separately. The Karhunen}Loève transfo...

Fuzzy Clustering of Image Trademark Database and Preprocessing using Adaptive filter and Karhunen-LOèVE Transform

In this paper an efficient preprocessing module has been described which focuses on building a trademark database that can be used for developing a trademark retrieval system. The preprocessing module focuses on noise removal from the trademark images using an adaptive filtering technique using Wiener filters, followed by Karhunen-Loève Transform that makes the trademark search process rotation...
