摘要
图像的特征提取是图像的识别和分类、基于内容的图像检索、图像数据挖掘等研究内容的基础性工作,其中图像的纹理特征对描述图像内容具有重要意义,纹理特征提取已成为目前图像领域研究的热点。文中深入研究了基于灰度共生矩阵(GLCM)的纹理特征提取方法,给出了基于Matlab的简便实现代码,分析了共生矩阵各个构造参数对构造共生矩阵的影响。分析结果对优化灰度共生矩阵的构造、实现基于灰度共生矩阵(GLCM)的特定图像的纹理特征提取等都具有重要参考意义。
The texture feature extraction of image is a foundational work for image recognition and classification, content-based image re trieval ,image data mining, etc. The texture feature of image is significant for description of image content. And it is a hot topic in the re search of image now. The method of texture feature extraction based on gray level co-occurrence matrix （GLCM） was studied. Analyzed the effect of each parameter on constructing the co-occurrence matrix and implemented the feature extraction using Matlab. The analytical results provide valuable reference for creating GLCM better and extracting texture features of specific kinds of images.
