The TEXRET-System, a texture retrieval system based on soft-computing technologies is being developed. The importance of this kind of system is increasing due to the massive access to digital image databases, which also demand the existence of systems that can understand human high-level requests. The TEXRET system has the following features: (i) direct access from the Internet, (ii) high inter...

Texture synthesis has grown into a mature field in computer graphics, allowing the synthesis of naturalistic textures and images from photographic exemplars. Surprisingly little work, however, has been dedicated to synthesizing tileable textures, that is, textures that when laid out in a regular grid of tiles form a homogeneous appearance suitable for use in memory-sensitive real-time graphics ...

A fast color-based algorithm for recognizing colorful objects and colored textures is presented. Objects and textures are represented by just six numbers. Let r, g and b denote the 3 color bands of the image of an object (stretched out as vectors) then the color angular index comprises the 3 inter-band angles (one per pair of image vectors). The color edge angular index is calculated from the i...

The statistical method in texture image analysis was applied to area extraction of biological objects from thin section electron microscope images. Four standard estimators defined from the gray level co-occurrence matrix, called 'inverse difference moment,' 'angular second moment,' 'entropy' and 'contrast,' were especially examined using a test pattern consisting of 6 artificial textures and t...

urban effete textures are multiple problems at conspectus skeletal, environmental, social and economic that encounter life of inhabitants with problem in this texture. according to the research, almost 90% of population in country exposed hazard of occurrence earthquake. in this face, by reason of problems, effete textures are over damage if the earthquake happened. nonetheless, to make provisi...

To achieve high accuracy in classification the present paper proposes a new method on texton pattern detection based on wavelets. Each texture analysis method depends upon how the selected texture features characterizes image. Whenever a new texture feature is derived it is tested whether it precisely classifies the textures. Here not only the texture features are important but also the way in ...

Texture boundary detection (or segmentation) is an important capability in human vision. Usually, texture segmentation is viewed as a 2D problem, as the definition of the problem itself assumes a 2D substrate. However, an interesting hypothesis emerges when we ask a question regarding the nature of textures: What are textures, and why did the ability to discriminate texture evolve or develop? A...

This work studies the preattentive discrimination of achromatic textures composed of mixtures of different (Weber) contrasts. These textures differ not at all in local spatial structure, but only in the relative proportions of different contrasts they comprise. It is shown that, like chromatic discrimination, preattentive discrimination of such textures is three-dimensional. The current results...

Textures appear in most natural images, but there is no precise mathematical definition of a texture. However, there are various descriptions of textures available in the literature. These approaches can be broadly classified as structural or deterministic, and stochastic [5, 7, 12, 19, 29]. The structural approach is more suitable for describing textures that can be formed by repeating a unit ...
