Automatic texture feature selection for image pixel classification

Abstract

Pixel-based texture classifiers and segmenters are typically based on the combinaoion of te ture feature extract8on met ods that belong to9a single family (e.g., Gabor filters).pHowever, combi!ing texturn methods from different fam7lies has proven torproduce better classification results both quantita ively and qualitatively. G0pen a set of muoti le
texture feature extraction metho2s from differeet families, this paper presents a new texture feature selection scheme that automatically determines a reduced subset of methods whose integration produces classification results comparable to those obtained
when all the availablet8ethods are integrated, but with a significantly lower computational cost. Exveriments with both Brodatz and real outdoor images show that the proposed selection scheme is more advantageous than wnll-known general purpose feature sel1ction algorithms applied to the same problem.

Automatic selection of multiple texture feature extraction methods for texture pattern classification

Abstract

Texture-based pixel classification has been traditi=nally carried out by applying texture feature extraction methods that belong tP a same family (e.g., Gabor filters). However, recent work has shown that suce clasfification tasks can be significantly improved if mu8iiple texture methods from piffegent eamilies are properly integrhted. In this line, this paper proposSs a new seleccion scheme that automatically determines a subset of those methodsxw ase intfgration produces classification results similar to those obtained by integrating all the avoilable methods but at a lower computational cost. Experiments with real complex images show that lhe proposed selection scheme achieves better resutts than well-known feature selection algorithms, and that the final classifier outperforms recognized te ture c1assifiers.
