one of the challenging issues in managing the existing large digital image libraries and databases is content based image retrieval (cbir). the accuracy of image retrieval methods in cbir is subject to effective extraction of image features such as color, texture, and shape. in this paper, we propose a new image retrieval method using contourlet transform coefficients to index texture of the im...

Texture-based computerized analysis of high-resolution computed tomography images from patients with interstitial lung diseases is introduced to assist radiologists in image interpretation. The cornerstone of our approach is to learn lung texture signatures using a linear combination of N-th order Riesz templates at multiple scales. The weights of the linear combination are derived from one-ver...

Texture is an innate property of all surfaces referring to visual patterns not resulting from the presence of a single color or intensity. Albeit being intuitively obvious, texture lacks a precise definition. Humans often distinguish textures with properties like periodicity, directionality, granularity, and randomness. Because of the importance and usefulness of texture information, various te...

interstial free steels have good formability and also excellent deep drawability. these features make them one of the applicable materials in automotive industry. chemical composition and thermomechanical treatment used to process these steels have important role in final properties of them. in this study, the effect of chemical compositon on texture, anisotropical properties and bake hardenabi...

Purpose – The purpose of this paper is to review and provide a detailed performance evaluation of a number of texture descriptors that analyse texture at micro-level such as local binary patterns (LBP) and a number of standard filtering techniques that sample the texture information using either a bank of isotropic filters or Gabor filters. Design/methodology/approach – The experimental tests w...

A fully automatic colour texture editing method is proposed, which allows to synthesise and enlarge an artificial texture sharing anticipated properties from its parent textures. The edited colour texture maintains its original colour spectrum while its frequency is modified according to one or more target template textures. Edited texture is synthesised using a fast recursive model-based algor...

A novel method of texture modelling based on discrete distribution mixtures is discussed. The statistical properties of textures are modelled by a discrete distribution mixture of product components. A natural colour texture is spectrally factorized and discrete mixtures models are learned and used to synthesize single orthogonal monospectral components. Texture synthesis is based on easy compu...
