چکیده

Most of the natural textures are non-homogenous and stochastic by nature. In many cases these textures are also directional. In this paper we present a method for the retrieval of the non-homogenous directional textures. This method is directional histogram and it represents the directional distribution of the texture. The histogram can be formed using either directional filtering method or Hough transform. We test the retrieval ability of our methods using rock texture images. The directional histogram method gives clearly better retrieval results than Gabor features and co-occurrence matrix.

Comparison of Some Content-based Image Retrieval Systems with Rock Texture Images

Texture is commonly used feature in most of the content-based image retrieval systems. This texture retrieval ability can be also applied to rock texture. The retrieval of the rock texture is a demanding task because of special character of rock. In this paper some existing contentbased image retrieval systems are tested with a sample set representing clearly different rock images. The recall a...

Periodicity, Directionality, and Randomness: Wold Features for Perceptual Pattern Recognition

One of the fundamental challenges in pattern recognition is choosing a set of features appropriate to a class of problems. In applications such as image retrieval, it is important that features used by the system in pattern comparison provide good measures of \perceptual similarity." We present here a new set of features and an image model based on the three mutually orthogonal components produ...

An efficient computation method for the texture browsing descriptor of MPEG-7

In this paper, an efficient computation method for computing the texture browsing descriptor of MPEG-7 is provided. Texture browsing descriptor is used to characterize a texture’s regularity, directionality and coarseness. To compute the regularity of textures, Fourier transform is first performed. To get more discriminative features for regularity computation, the Fourier spectrum is treated a...

Data mining on non-homogenous textures

Clustering of the texture images is a demanding part of multimedia database mining. Most of the natural textures are non-homogenous in terms of color and textural properties. In many cases, there is a need for a system that is able to divide the non-homogenous texture images into visually similar clusters. In this paper, we introduce a new method for this purpose. In our clustering technique, t...

Co-occurrence Features of Multi-scale Directional Filter Bank for Texture Charcterization

In this paper, we propose to use co-occurrence components. Spatial correlation of wavelet coefficients due features computed from multi-scale directional filter bank to the structure of textures can be captured by the co(MDFB) for texture characterization. As the filter band occurrence features. In this paper, we propose to use cocoefficients are localized frequency components, features from oc...
