Textures can describe a wide variety of natural phenomena with random variations over repeating patterns. Examples of textures include images, motions, and surface geometry. Since reproducing the realism of the physical world is a major goal for computer graphics, textures are important for rendering synthetic images and animations. However, because textures are so diverse it is difficult to de...

Topological magnetic states, such as chiral skyrmions, are of great scientific interest and show huge potential for novel spintronics applications, provided their topological charges can be fully controlled. So far skyrmionic textures have been observed in noncentrosymmetric crystalline materials with low symmetry and at low temperatures. We propose theoretically and demonstrate experimentally ...

Dynamic textures are image sequences which contain moving scenes such as a flowing river, drifting smoke, waving foliage, etc. Such image sequences have dynamical properties that are related to motion in the physical world. In this paper, we propose a novel analytical tool for analyzing dynamic textures. The key idea is to exploit the properties of the impulse responses of the state variables c...

We propose a geometric ansatz, a restriction on Euclidean / Minkowski distance in the embedding space being propotional to distance in the embedded space, to generate spacetimes with vanishing gravitational mass (Riku iuk = 0, uiu i = 1). It turns out that these spacetimes can represent global monopoles and textures. Thus the ansatz is a prescription to generate zero mass spacetimes that could ...

Abstract In this study, mainly, we introduce the category Tex of textures and texturally continuous functions. Relations with some other categories, particulary dfTex, fTex, are pointed out. It is shown that the categories CTop of C-spaces and a full subcategory of Sober of sober spaces are, respectively, isomorphic to Tex and STex of simple textures. Some properties discussed including the exi...

Dynamic textures encompass the class of video sequences that exhibit some stationary properties in time. Examples of such textures include ripples on water, smoke out of a chimney, waving flags etc. Recently, it has been shown that such textures can be expressed as the output of a linear dynamic system that can be identified from a sample image sequence. In this paper, we propose to identify th...

This paper presents a novel filtering-based method for decomposing an image into structures and textures. Unlike previous filtering algorithms, our method adaptively smooths image gradients to filter out textures from images. A new gradient operator, the interval gradient, is proposed for adaptive gradient smoothing. Using interval gradients, textures can be distinguished from structure edges a...

We show that it is possible to fully determine the neutrino mass spectrum from two-zero textures of the neutrino mass matrix. As a consequence, definite predictions can be obtained for the neutrinoless double beta decay. Electronic address: [email protected] Mailing address 1 In the flavor basis where the charged lepton mass matrix is diagonal, a phenomenological analysis of two-zero textu...

Weak dipolar effects in atomic Bose-Einstein condensates (BECs) have recently been predicted to develop spin textures. However, observation of the spin textures requires us to decrease the magnetic field down to approximately 10 microG for spin-1 alkali BECs, so that they are not washed out by the Zeeman effect. We present a scheme to observe the magnetic dipole-dipole interaction in alkali BEC...
