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

This monthly journal, begun in 1950, is devoted entirely to research in pure and applied mathematics, principally to the publication of original papers of moderate length. A section called Shorter ...

The method of empirical orthogonal function analysis is applied to wind stress vectors over the tropical Pacific Ocean from 1961 through 1978. It is determined that this vector analysis enables a more ...
