The objective of this paper is to present a simple framework for the derivation and analysis of orthogonal IIR transfer functions, which are directly related to orthogonal rational functions.

ABSTRACT The complexity inherent in climate data makes it necessary to introduce more than one statistical tool to the researcher to gain insight into the climate system. Empirical orthogonal function ...

Orthogonal moments have emerged as robust mathematical descriptors in image analysis and pattern recognition, offering a compact and invariant representation of image features.
