Texture synthesis aims to define and reproduce discriminating image features. These features are used to associate with and differentiate between two textures. Often texture is composed of a pattern with an element of randomness in each feature’s appearance, position and orientation. The goal is to imitate the sample texture in such a way that sample and synthesised texture are perceived to be ...

Measured material representations like Bidirectional Texture Functions or Reflectance Fields offer very realistic appearance but the user is currently not capable of changing this appearance in an effective and intuitive way. Such editing operations would require a low-dimensional but expressive model for appearance that exposes only a small set of intuitively editable parameters (1D-sliders, 2...

Diamond tilms were deposited with an r.f. plasma operating at atmospheric pressure. The gas composition above the growth surface was measured with a gas ch~-omatograph. Experiments were conducted over a range of methane flow rates and sut'strate t,,'r~peratt~res. Films were characterized by SEM and X-ray diffraction texture analysis. Increases in either input methane-hydrogen ratio or substrate...

This paper presents new fixed-rate texture compression systems for RGB and RGBA images, which use variable precision differential encoding for the color codewords, resulting in reduced compression artifacts, in particular for smooth color variations. Experiments using hundreds of textures show that they achieve higher quality than the commonly used S3TC at the same compression ratio or (for RGB...

In order to improve the visual effect of AR live video detail texture, an adaptive enhancement algorithm based on approximate matching is proposed. According local self-similarity original image, best block initial super-resolution image obtained. After extracting its high-frequency information, improved singular value decomposition (SVD) used embed watermark into gray image; And through extrac...

This study was conducted to investigate surface characteristics of sand particles. Surface topography of sand particles was determined in 3-D using a commercially available optical profiler. Measurements were made on areas that had side dimensions on the order of 0.1 mm at a lateral resolution of 0.3 Ilm and height resolution of less than 6 nm. The 3-D representation of a surface obtained using...

Textures have been used in various applications, such as carpet quality control, region recognition in satellite images, and body painting control in the vehicle industry. This paper studies texture synthesis. We survey the algorithms for synthesizing textures that have proposed over the past two decades. A variety of algorithms associated with synthesized textures are given. The goal is to fur...
