In image processing, a static texture is defined as an image showing spatial stationarity, while A dynamic texture is a sequence of images characterized by temporal as well as spatial stationary nature. Dynamic Texture synthesis is the process of producing artificial Dynamic textures starting from a given sample texture. Videos representing flames, water, smoke, etc. are often defined as dynami...

In this paper, an approach for integrating multiresolution representations of terrain geometry and terrain texture data is presented. A terrain is modeled by a regular grid, which can be partially refined by local TINs in order to represent morphologically complex terrain parts. The multiresolution models for terrain texture data and geometry data are closely related: The rendering algorithm se...

In this paper, we study texture metamorphosis, or how to generate texture samples that smoothly transform from a source texture image to a target. We propose a patternbased approach to specify the feature correspondence between two textures, based on the observation that many texture images have stochastically distributed patterns which are similar to each other. First, the user selects a patte...

Textures, textural transformation, and formation and annihilation of a single vortex were investigated in narrow cylinders with 100 microm radius in A-phase under rotation up to 6.28 rad/sec. Three textures were found, depending on the cooling conditions of the sample through the superfluid transition temperature T(c). We found the gyromagnetic effect of textures; that is, two textures (A or B)...

This paper presents an intensity-based iris recognition system. The system exploits local intensity changes of the visible iris textures such as crypts and naevi. The textures are extracted using local histogram equalization and the proposed ‘quotient thresholding’ technique. The quotient thresholding partitions iris images in a database such that a ratio between foreground and background of ea...

Texture images are a special class of images that are spatially homogeneous and consist of repeated elements, often subject some randomization in their location, size, color, orientation, etc. Textures can be classified into different classes or groups based on their structure and origin. Figure 1 gives some example textures. Textures are widely used in varied fields ranging from bio medical im...

A force-feedback Phantom device, a custom-built vibrotactile dataglove, and embossed paper sheets are compared to detect different textures. Two types of patterns are used, one formed by different geometrical shapes, and the other with different grooves width. Evaluation shows that the vibrotactile dataglove performs better in the detection of textures where the frequency of tactile stimuli var...

Mapping Textures on 3D Terrains: A Hybrid Cellular Automata Approach. (December 2005) Swapnil Sinvhal, B.Arch., Indian Institute of Technology, Roorkee, India Chair of Advisory Committee: Dr. John Keyser It is a time consuming task to generate textures for large 3D terrain surfaces in computer games, flight simulations and computer animations. This work explores the use of cellular automata in ...

This study investigates the effect of update rate on the quality of haptic virtual textures, with the goal to develop a guideline for choosing an optimal update rate for haptic texture rendering. Two metrics, control stability and perceived quality of the virtual haptic texture, were used. For control stability, we examined the effect of update rate on the “buzzing” of virtual haptic textures. ...

We point out a generic correlation between the Friedberg-Lee symmetry of quark mass operators and the vanishing of quark masses. We make phenomenological explorations on two textures of quark mass matrices with the broken Friedberg-Lee symmetry. We present a new pattern of quark mass matrices in agreement with current experimental data. Both analytical and numerical results of our calculations ...
