Abstract: Automatic classification of texture image is a key task in many fields, including agricultural products classification, visual scene detection, information retrieval, medical applications, and so on. When operating directly on the image, the traditional classification method as the data of high dimension characteristic performance is poor, it is difficult to obtain good effect. But the Support Vector Machine (SVM) can e the defects very high-dimensional said, was widely used in the texture image classification.
In this paper, the main work done is as follows:
1. The brief analysis of the working principle of support vector machine, analyzing each parameter of kernel function of support vector machine on the classification model, the influence paring the parameters of the SVM optimization ability. At the same time simple introduces the application of SVM in the texture image classification.
2. For gray image using gray level co-occurrence matrix method, Tamura method and Gabor filtering method respectively to extract image texture feature, pared three methods of classification the stone and bark two texture image. This paper analyzes the graylevel co-occurrence matrix as a kind of method.
3. Application of SVM for texture image classification algorithm for Dwarf bunt and Stinking sample training and these two kinds of
