In this paper we propose a motion based approach for synthesizing dynamic textures. Dynamic textures are natural phenomenon characterized by their distinctive motion patterns. Synthesis of these textures is thus considered as the regeneration of a motion pattern that has identical motion distribution of a source texture. In this paper we propose a synthesis technique where new textures are gene...

Photographs and images often have regions which are in some sense flawed. Often, there may be a stain or an undesired feature covering a significant portion of the image, and an algorithm that can “fix” the image is desired. We propose a technique based on Heeger and Bergen’s texture synthesis algorithm [4]. By integrating a composition step into the aforementioned algorithm, one portion of the...

A texture synthesis method is presented that generates similar texture from an example image. It is based on the emulation of simple but rather carefully chosen image intensity statistics. The resulting texture models are compact and no longer require the example image from which they were derived. They make explicit some structural aspects of the textures and the modeling allows knitting toget...

We propose a texture analysis method based on Rényi’s generalized entropies. The method aims at identifying texels in regular textures by searching for the smallest window through which the minimum number of different visual patterns is observed when moving the window over a given texture. The results show that any of Rényi’s entropies can be used for texel identification. However, the second o...

We present an application of texture synthesis in creating collages. We use the texture synthesis method proposed by Ashikhmin [1] to selectively copy patches of the source image onto the image to be stylized, creating an automatic collage. The underlying algorithm is fast and allows the user to iteratively improve the quality of the resulting image. We show the use of this algorithm in capturi...

We take a look at texture analysis research over the past 25 years, from the persective of the Human Vision and Electronic Imaging conference. We consider advances in the understanding of human perception of textures and the development of texture analysis algorithms for practical applications. We cover perceptual models and algorithms for image halftoning, texture discrimination, texture segme...

Mapping textured images on smoothly approximated surfaces is often used to conceal the loss of their real, fine-grained relief. A limitation of mapping a fixed texture in such cases is that it will only be correct for one viewing and one illumination direction. The presence of geometric surface details causes changes that simple foreshortening and global color scaling cannot model well. Hence, ...

Since the introduction of texture synthesis using a reactiondiffusion model in the early 1990s their use has not been widespread. This is likely due to both the difficulty in selecting parameters that result in stable, useful patterns as well as, the computational costs of producing these patterns. In this paper we present techniques that help overcome the difficult parameter selection process ...

Image quilting is a texture synthesis technique to create a large texture by wrapping around patches of a small texture in a way that the repetition of small texture is not noticeable. The basic algorithm is to randomly select small patches in a given texture. These patches are then positioned in a large texture to be synthesized and blended across boundaries to remove the appearance of boundar...
