In this paper, we propose a novel local feature descriptor, Local Gaussian Structural Pattern (LGSP), for face recognition that encodes the directional information of the face’s textures (i.e., the texture’s structure), producing a more discriminant code than other state-of-the-art methods. Each micro-pattern’s structure is computed by using a derivative-Gaussian compass mask, which is more rob...

Micro-scale fluids are tiny droplets that adhere to the surface of an object as a result rainfall, perspiration, etc. fluid simulation is widely used in fields such film and games. The existing state-of-the-art methods not suitable for simulating water moving on due fact cannot leave texture space their movements always depend continuous UV region. In this study, novel method proposed. We divid...

The Merensky Reef hosts one of the largest PGE resources globally. It has been exploited for nearly 100?years, yet its origin remains unresolved. In present study, we characterised eight samples reef at four localities in western Bushveld Complex using micro-X-ray fluorescence and field emission scanning electron microscopy. Our results indicate that formed through a range diverse processes. Te...

It is known that the mechanical behavior of many hexagonal close-packed (HCP) materials sensitive to textural variations. In technologically important magnesium (Mg) alloys, anisotropic plastic behaviors and their dependence on different processing-induced textures have been reasonably well studied under relatively simple stress states. However, a detailed assessment rate-dependent microstructu...

A texture synthesis method is presented that generates similar texture from an example image. It is based on the emulation of simple but rather carefully chosen image intensity statistics. The resulting texture models are compact and no longer require the example image from which they were derived. They make explicit some structural aspects of the textures and the modeling allows knitting toget...

We propose a set of Yukawa textures for the Dirac and Majorana Yukawa mass matrices of the neutrinos. These set of textures have one parameter in the Majorana sector and no free parameters in the Dirac sector. We show that such textures can lead to a successful prediction for the squared mass differences relevant to solar, atmospheric and LSND neutrino oscillation experiments. Furthermore a pai...

This paper is concerned to the application of a relatively new image texture segmentation algorithm named Hidden Markov Tree (HMT) to the detection of micro-calcification clusters in mammograms. The HMT is a wavelet-based tree-structured probabilistic graph that can capture the statistical properties of the coefficients of the wavelet transform. The aim of this approach is, on the one hand, to ...

Understanding the influence of surface properties (roughness, grooves, discrete textures/dimples) on the performance of hydrodynamically lubricated contacts has been the aim of numerous studies. A variety of different numerical models have been employed by many researchers in order to find optimal texturing parameters (shape, size, distribution) for best performance enhancement in terms of load...
