Texture Particles

Abstract

International audienceThis paper presents an analytical extension of texture synthesis techniques based on the distribution of elementary texture components. Our approach is similar to the bombing, cellular, macrostructured and lapped textures techniques, but provides the user with more control on both the texture analysis and synthesis phases. Therefore, high quality results can be obtained for a large number of structured or stochastic textures (bricks, marble, lawn, etc.). The analysis consists in decomposing textures into elementary components -- that we call ''texture particles'' -- and for which we analyze their specific spatial arrangements. The synthesis then consists in recomposing similar textures directly on arbitrary surfaces by taking into account the previously computed arrangements, extended to 3D surfaces. Compared to ''pixel-based'' analysis and synthesis methods, which have been recently generalized to arbitrary surfaces, our approach has three major advantages: (1) it is fast, which allows the user to interactively control the synthesis process. This further allows us to propose a large number of tools, granting a high degree of artistic freedom to the user. (2) It avoids the visual deterioration of the texture components by preserving their shapes as well as their spatial arrangements. (3) The texture particles can be not only images, but also 3D geometric elements, which extends significantly the domain of application

Real-time structured texture synthesis and editing using image-mesh analogies

“…In [1] feature distributions can be controlled using a user-drawn feature probability map. In [4,29] feature sizes, orientations and so forth can be modified. In [19,30], the difficult problem of smooth transitions between different types of textures is addressed.…”

“…In [19,30], the difficult problem of smooth transitions between different types of textures is addressed. As for texture particles [4], [30] considers elementary texture components (textons) by using texton masks. We therefore call such techniques texton-based.…”

“…Our approach mainly extends the texture particles and texton masks approaches of respectively [4] and [30] by further bounding individual textons with polygons. Since our polygons may be considered to some extent as cells, our approach comes also close to cellular texture synthesis approaches, which have already been used successfully long before in the field of pure texture synthesis (that is, without analysis), for example for generating brick-wall patterns [21,16] or noise functions [25].…”

“…As for texton-based techniques [4,30], the first step consists of texture segmentation, which means that we need to identify textons by creating a binary image I s (i, j) from the input texture image I(i, j). In [30], such an image is called texton-mask.…”

Uniform texture synthesis and texture mapping using global parameterization

“…Hybrid methods [20] lay out patches and use pixel-based algorithm to hide the seams. Surface texture synthesis extends these 2D texture synthesis methods to synthesize texture directly on the surface, including pixel-based methods [31,29,33,27] and pattern mapping methods [21,23,25,5]. With these methods, the discontinuities and cracks almost disappear, while the distortion problem is greatly reduced.…”
