TLDR
In this paper, three standard approaches to automatic texture classification make use of features based on the Fourier power spectrum, on second-order gray level statistics, and on first-order statistics of gray level differences, respectively.
Abstract
Three standard approaches to automatic texture classification make use of features based on the Fourier power spectrum, on second-order gray level statistics, and on first-order statistics of gray level differences, respectively. Feature sets of these types, all designed analogously, were used to classify two sets of terrain samples. It was found that the Fourier features generally performed more poorly, while the other feature sets all performned comparably.

Content-Based Medical Image Retrieval

TL;DR: This chapter introduced content-based image retrieval (CBIR) and its key components and would therefore be useful as a training tool for medical students, residents, and researchers to browse and search large collections of disease-related illustrations using their visual attributes.

Descriptor learning based on fisher separation criterion for texture classification

TL;DR: A learning framework of image descriptor is designed based on the Fisher separation criteria (FSC) to learn most reliable and robust dominant pattern types considering intraclass similarity and inter-class distance and it is found that such a learning technique can largely improve the discriminative ability and automatically achieve a good tradeoff between discrim inative power and efficiency.

Particulate matter characterization by gray level co-occurrence matrix based support vector machines

TL;DR: The proposed GLCM-based approach of training SVM predicts a robust and more accurate segmentation algorithm than the standard histogram technique, as additional information based on the spatial relationship between pixels is incorporated for image classification.

A novel image mining technique for classification of mammograms using hybrid feature selection

TL;DR: A hybrid approach of feature selection is proposed, which approximately reduces 75% of the features, and new decision tree is used for classification, and the accuracy obtained is approximately 97.7%, which is highly encouraging.

Computer description of textured surfaces

TL;DR: This work deals with computer analysis of textured surfaces with descriptions of textures formalized from natural language descriptions obtained from the directional and non-directional components of the Fourier transform power spectrum.

Spectral and textural processing of ERTS imagery

TL;DR: In this article, a procedure is developed to simultaneously extract textural features from all bands of ERTS multispectral scanner imagery for automatic analysis, and an ellipsoidally symmetric functional form is assumed for the co-occurrence distribution of multiimage greytone N-tuple differences.
