چکیده

Texture classification is a problem that has been studied and tested using different methods due to its valuable usage in various pattern recognition problems, such as wood recognition and rock classification. The Grey-level Co-occurrence Matrices (GLCM) and Gabor filters are both popular techniques used on texture classification. This paper combines both techniques in order to increase the accuracy. The paper used 32 textures from the Brodatz texture dataset with 1024 training samples and 1024 testing samples. GLCM achieved a recognition rate of 84.00%, Gabor filters achieved 79.58% while combination of GLCM and Gabor filters achieved a recognition rate of 88.52%, which is better than both methods. The experiments showed that the best result can be achieved by using a GLCM with grey level of 16, spatial distance of one pixel and combine with Gabor features decomposed to six features.

Scene Image Analysis using GLCM & Gabor Filter

In this paper, images of realworld natural scenes and manmade structures of different depth are taken. With increase in image depth , roughness increases in case of man-made structures whereas natural scene images become smooth, thus reducing the local roughness of the picture. Such kind of specific arrangement produces a particular spatial pattern of dominant orientations and scales that can b...

Texture segmentation is the process of partitioning an image into regions with different textures containing a similar group of pixels. Detecting the discontinuity of the filter's output and their statistical properties help in segmenting and classifying a given image with different texture regions. In this proposed paper, chili x-ray image texture segmentation is performed by using Gabor filte...

Gabor Filters as Feature Images for Covariance Matrix on Texture Classification Problem

The two groups of popularly used texture analysis techniques for classification problems are the statistical and signal processing methods. In this paper, we propose to use a signal processing method, the Gabor filters to produce the feature images, and a statistical method, the covariance matrix to produce a set of features which show the statistical information of frequency domain. The experi...

A Comparison of Texture Models for Automatic Liver Segmentation

Automatic liver segmentation from abdominal computed tomography (CT) images based on gray levels or shape alone is difficult because of the overlap in gray-level ranges and the variation in position and shape of the soft tissues. To address these issues, we propose an automatic liver segmentation method that utilizes low-level features based on texture information; this texture information is e...

Algorith Based on Medium Co-occurrence Matrix for Image Region Classification

The paper presents a method for the classification and identification of texture image regions. To compare regions, a data base with single texture images is used. The dimension of the reference images is greater than the analyzed region dimension. For the proper region recognition a decision theoretic method and two types of statistic texture feature are used. The first type features are the p...
