Paper Abstract

This paper presents new techniques for the texture classification of regions based on edge co- occurrence matrices and discrete Hermite functions which are used to describe them. The paper briefly defines co-occurrence matrices and how they can be used to describe the relationship of edges around a pixel. Texture is interpreted as a measure of the edginess about a pixel and is described by edge co-occurrence matrices. The texture of the region is characterized by an orthogonal decomposition of the co-occurrence matrix using 2-dimensional discrete Hermite functions. The coefficients of this decomposition provide a low order feature vector which can be used for texture classification. The coefficients of the Hermite functions used in the decomposition of the co-occurrence matrix are analyzed by two neural network classifiers: the multilayer perceptron and the cascade correlation. Experiments have been performed for the training and validation of the networks on two types of terrain (grass and trees) taken from FLIR images during a low level approach to a bridge.
