T exture analysis is the extraction of textural features from images (Tuceryan and Jain, 1998). The meaning of texture varies, depending on the area of science in which it is used. In general, texture refers to the physical character of an object or the appearance of an image. In image analysis, texture is defined as a function of the spatial variation in intensities of pixels (Tuceryan and Jai...

to study the effects of scale and tillage management on variability of soil properties in adjacent lands of different tillage type, soil sampling was performed linearly along contour line from the middle position of slope with 5 m intervals. in overall, 45 soil samples were collected from a field with conventional up-down tillage and 40 samples from an adjacent filed with contour tillage. soil ...

the permeability and the power losses are very important properties of non-oriented electrical sheets. the existence of a crystallographic easy magnetization plane and direction makes the distribution of grain orientations (texture) the most important factor in the improvement of the quality of a soft magnetic material [1]. the optimum texture is a fibre texture in which all the grains have a <...

Introduction The texture is " A measure of the variation of the intensity of a surface, quantifying properties such as smoothness, coarseness, and regularity. " Textures are homogenous visual patterns in a scene such as grass, cloud, wood, and sand. Although the stated definition is an acceptable one, Zucker and Kant described the textures as: "Texture is an apparently paradoxical notion. On th...

Recent models of texture processing use low level, spatially parallel computations to extract texture properties. The rapid, preattentive nature of texture segregation suggests that these computations are bottom-up in nature. However, the immunity of texture judgments to top-down influences remains to be tested. Here we investigate the degree to which judgments of texture orientation are suscep...

BACKGROUND Only a few texture measures can be used for texture characterization of infarcted myocardium and detection of reperfused myocardium early after infarction. This study was conducted to establish the relationship between texture properties of infarcted myocardium and infarct-related artery patency by quantitative computer analysis of 2-dimensional echocardiographic images with the wave...

kefiran, extracted from kefir grains, is a water-soluble, glucogalactan containing almost equal amounts of d-glucose and d-galactose residues. throughout this research, kefiran and xanthan were added at concentrations of 3% (w/w flour basis) to two wheat dough samples to investigate the effects on the rheological and physical properties of french bread. physicochemical properties of wheat and i...

The most defining characteristic of texture is its underlying geometry. Although the appearance of texture is as dynamic as its illumination and viewing conditions, its geometry remains constant. In this work, we study the fundamental characteristic properties of texture geometry—self similarity and scale variability—and exploit them to perform surface normal estimation, and geometric texture c...
