摘要: 针对LBP(局部二值模式)纹理描述子局限于在单一分辨率下捕获纹理图像的纹理信息的问题,提出一种基于多分辨率的厄米高斯矩的LBP纹理分类方法。首先结合图像纹理的多分辨率特性,采用厄米高斯矩对图像进行多分辨率重构,然后利用LBP纹理描述子对重构图像进行特征提取,最后采用K近邻特征空间距离的分类方法进行纹理分类。选取KTH-TIPS纹理数据库的纹理图像进行测试实验,实验结果表明,与传统LBP纹理分类方法相比,使用多分辨率的厄米高斯矩的LBP纹理分类方法进行纹理分类,可以更加全面地描述图像的纹理信息,使纹理分类准确率更高。

Abstract: LBP(Local Binary Pattern)as a texture descriptor to capture images of local texture information in a single resolution, a method based on multi-resolution of the Gaussian-Hermite moments and LBP texture classification is proposed. Firstly, with the multi-resolution characteristic of image texture, the multi-resolution of the Gaussian-Hermite moments is used to reconstruct image. Then LBP is used for the feature extraction of reconstruction image. Finally, the K-nearest neighbor feature space distance method is used to classify image texture. KTH-TIPS texture library images are selected for texture classification test, the experimental results show that compared with the traditional LBP texture classification method, the method based on multi-resolution of the Gaussian-Hermite moments and local binary pattern texture classification is used to texture classification, which make more comprehensive to describe the image texture information to get higher classification accuracy.
