Analysis and Synthesis of Structural Textures

2000
With the advent of image based modeling techniques, it becomes easier to apply textures extracted from reality onto virtual worlds. Many repetitive patterns (structural textures) in human constructions can be parametrized with procedural textures. These textures offer a powerful alternative to traditional color textures, but they require the artist to ...

Data-Embeddable Texture Synthesis

2007
Data hiding techniques onto images provide tools for protecting copyright or sending secret messages, and they are currently utilized as a simple input device of a cell phone by detecting a data embedded in an image with an equipped digital camera. This paper presents a method of synthesizing texture images for embedding arbitrary data by utilizing the

Clustering and blending for texture synthesis

Pattern Recognition Letters, 2004
We consider texture modeling techniques which are exemplar-based, i.e. techniques which use several example texture images to learn pixel arrangements. The motivation for these techniques is that the structure of a texture can be characterized by the spatial distribution of pixels in a neighborhood of the image or the multiresolution pyramid.

Near-Regular Texture Synthesis

2009
This paper describes a method for seamless enlargement or editing of difficult colour textures containing simultaneously both regular periodic and stochastic components. Such textures cannot be successfully modelled using neither simple tiling nor using purely stochastic models.

Sequential synthesis of natural textures

Computer Vision, Graphics, and Image Processing, 1985
Abstract A new method for the generation of natural textures is presented. Using a priori-given second-order statistics (second-order spatial averages or autocorrelation parameters) of a natural texture field as input, a procedure is given to synthesize an artificial texture field in such a way that its second-order statistics are equal to the ...

An Improved Texture Synthesis Algorithm

2015
In order to improve the speed of texture synthesis, we propose an improved synthesis algorithm according to the Image Quilting algorithm in this paper. In this algorithm, the L-overlap region is replaced by r-overlap region to reduce the amount of the pixels used to compute the error of Sum-of-Squared Differences SSD and to lower the calculation ...

Feature-Based Texture Synthesis

2005
We introduce a new method for texture synthesis on regular and irregular example textures. In this paper, an enhanced patch-based algorithm is proposed to select patches with the best structural similarity and to avoid discontinuity at the boundary of adjacent patches.

Textures for realistic image synthesis

Computers & Graphics, 1985
Abstract An important aspect in generating images of real materials and surfaces is the contribution of the visual effects of textures. This study presents methods for simulating a variety of different textures. Two general types of texture, geometric and spectral, are simulated. Geometric textures incorporate the irregularities and variations which

Statistical Invariance for Texture Synthesis

IEEE Transactions on Visualization and Computer Graphics, 2012
Estimating illumination and deformation fields on textures is essential for both analysis and application purposes. Traditional methods for such estimation usually require complicated and sometimes labor-intensive processing. In this paper, we propose a new perspective for this problem and suggest a novel statistical approach which is much simpler and ...

Texture synthesis: textons revisited

IEEE Transactions on Image Processing, 2006
This paper introduces a technique for synthesizing natural textures, with emphasis on quasiperiodic and structural textures. Textures are assumed to be composed of three components, namely illumination, structure, and stochastic. The contribution of this work is that, in contrast to previous techniques, it proposes a joint approach for handling the ...
