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...

Many interesting real-world textures are inhomogeneous and/or anisotropic. An inhomogeneous texture is one where various visual properties exhibit significant changes across the texture’s spatial domain. Examples include perceptible changes in surface color, lighting, local texture pattern and/or its apparent scale, and weathering effects, which may vary abruptly, or in a continuous fashion. An...

In this paper we present modern texture mapping techniques and several applications of polynomial texture mapping in cultural heritage programs. We also consider some well‐known and some new methods for mathematical procedure that is involved in generation of polynomial texture maps.

A new generative multispectral texture model based on discrete distribution mixtures is introduced. Statistical texture properties are represented by a discrete distribution mixture of product components. A natural colour or multispectral texture is spectrally factorized and discrete mixtures models are learned and used to synthesize single orthogonal monospectral components. Texture synthesis ...

Projective texture-mapping is a powerful tool for image-based rendering. However, visibility information must be obtained in order to project correct textures onto the geometric sturcture. This paper presents a novel visibility algorithm for determining which polygons are visible from each camera position. It has object-space precision, but operates in both image-space and object-space to get b...

Realistic rendering of computer modeled three dimensional surfaces typically involves estimation of the reflectance properties of the material to be used for rendering the surface, or use of photographs of the material for texturing instead. Bidirectional texture functions (BTFs) can be used for this purpose, however, full coverage of all viewing and lighting directions desired must be acquired...

This paper presents a new algorithm for synthesising image texture. Texture synthesis is an important process in image post-production. The best previous approaches have used non-parametric methods for synthesising texture. Unfortunately, these methods generally suffer from high computational cost and difficulty in handling scale in the synthesis process. This paper introduces a new idea of usi...

This paper reviews the literature on texture segregation and texture transparency, and proposes a new account of texture transparency based on the theory of texture segregation. To date, it has been suggested that the perception of transparency might stem from perceptual grouping or spacing effects between texture elements. Based on recent data, this paper argues that texture transparency shoul...

This paper presents an effective approach to generate a set of small textures from an input texture that can be tiled together to synthesize large textures. Such a small set can be useful in texturing any large area realistically and efficiently while consuming only a small amount of texture memory. Our approach is advantageous in its ability to generate a smaller number of tiles that can embed...
