Optimal Basis from Empirical Orthogonal Functions and Wavelet Analysis for Data Assimilation: Optimal Basis WADAi

Wavelet Analysis provides a new orthogonal basis set which is localized in both physical space and Fourier transform space. Empirical Orthogonal Functions (EOFs), on the other hand, provide a global representation of data sets. Here we investigate the various ways in which one can combine these basis sets for optimal representation of data. EOFs represent the global large scale information and ...

Image Coding Using Orthogonal Basis Functions

The transform properties of several orthogonal basis functions are analysed in detail in this report, and their performance compared using a set of grayscale test images, containing both natural and artificial scenes. Well-defined image quality measures are used to determine the type of images that are most suitable for compression for a given basis function. The particular transforms that we h...

Modeling impulse response using Empirical Orthogonal Functions

There is a growing need for acoustic channel simulators. Among the reasons for this is the increased interest in underwater acoustic communications, but also the fact that measuring the characteristics of the underwater channel is very expensive. A channel simulator provides access to realistic channels, and allows us to compare algorithms and modulations under identical conditions. Channel sim...
