In this paper a new character description method, based on the combination of structural and statistical approaches, is presented. Characters are preliminarily decomposed in terms of structural primitives (circular arcs) and successively described in terms of statistical features (geometric moments). The obtained description is much more stable and yields significant improvements in classificat...

Abstract Stochastic processes are encountered in many contexts, ranging from generation sizes of bacterial colonies and service times a queueing system to displacements Brownian particles frequency fluctuations an electrical power grid. If such Markov, then their probability distribution is governed by the Kramers–Moyal (KM) equation, partial differential equation that involves infinite number ...

Politano and Pouquet’s law, a generalization of Kolmogorov’s four-fifths law to incompressible MHD, makes it possible to measure the energy cascade rate in incompressible MHD turbulence by means of third-order moments. In hydrodynamics, accurate measurement of thirdorder moments requires large amounts of data because the probability distributions of velocity-differences are nearly symmetric and...

New Zernike velocity moments have been developed to describe an object, not only by its shape , but also by its motion throughout an image sequence. These are an extended form of the orthogonal Zernike moment set and include velocity information introduced via centralised moments. Initial analysis shows that they perform well when applied to analysing gait sequences resulting in a good recognit...

This paper proposed a method that combines Polar Fourier Transform, color moments, and vein features to retrieve leaf images based on a leaf image. The method is very useful to help people in recognizing foliage plants. Foliage plants are plants that have various colors and unique patterns in the leaf. Therefore, the colors and its patterns are information that should be counted on in the proce...

Lysine Lipoylation is a protective and conserved Post Translational Modification (PTM) in proteomics research like prokaryotes eukaryotes. It connected with many biological processes closely linked metabolic diseases. To develop perfect accurate classification model for identifying lipoylation sites at the protein level, computational methods several other factors play key role this purpose. Us...
