Four new methods for classification of multivariate binary data are presented, based on an orthogonal expansion of the density in terms of discrete Fourier series. The performance of these methods in ...

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 ...
