A Method of the Extraction of Texture Feature

2008
In order to understand the emotional information of the color image, research focus has been shifted from designing sophisticated low-level feature extraction algorithms to reducing the `semantic gap' between the visual features and the richness of human perception. In this paper, we firstly get the ROI using the Eye tracker and divide every image into

Texture Classification from Random Features

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2012
Inspired by theories of sparse representation and compressed sensing, this paper presents a simple, novel, yet very powerful approach for texture classification based on random projection, suitable for large texture database applications. At the feature extraction stage, a small set of random features is extracted from local image patches.

Fractal feature and texture analysis

Systems and Computers in Japan, 1988
AbstractAlthough fractal dimension is popular in computer graphics, it is not yet utilized adequately in image analysis. Thus, this paper presents an example of the application of fractal dimension to image analysis. First, the conventional fractal concept is described and then the possibilities of its application to image processing are discussed ...

Noise robustness of texture features

Image and Vision Computing, 1997
This note examines the noise robustness of two sets of texture features, one set derived from the popular multichannel filtering approach, and the other from the benchmark grey level co-occurrence matrix approach. Comparative experimental results are presented. The results clearly demonstrate the superiority of the multichannel approach.

Texture Features and Image Texture Models

2019
Image texture is an important phenomenon in many applications of pattern recognition and computer vision. Hence, several models for deriving texture properties have been proposed and developed. Although there is no formal definition of image texture in the literature, image texture is usually considered the spatial arrangement of grayscale pixels in a ...

Scale Sensitivity of Textural Features

2017
Prevailing surface material recognition methods are based on textural features but most of these features are very sensitive to scale variations and the recognition accuracy significantly declines with scale incompatibility between visual material measurements used for learning and unknown materials to be recognized.

Relational Features for Texture Classification

2011
Texture features play an important role in facilitating various applications, for instance, image retrieval and object recognition. In this work, we investigate the relational features as a texture descriptor in classifying materials and visual textures from their appearance.

MORPHOLOGICAL TEXTURAL FEATURES

Particulate Science and Technology, 1989
ABSTRACT This paper describes the statistical and mathematical models for the gray level surface. Morphological Textural Features (MTFs) derived from the models are invariants. They include: • Bessel-Fourier Coefficients • Measurments of Gray Level Distributions • Rotational Symmetry • Translational Symmetry • Coarseness • Contrast • Roughness ...

Combining Features for Texture Analysis

2015
In the present paper we consider building feature vectors for texture analysis by combining information provided by two techniques.The first feature extraction method the Discrete Wavelet Transform is applied to the entire image. By computing the Gini index for several subimages of a given texture, we choose one that maximizes this measure.
