多尺度Gabor小波变换在图像检索中的应用

在基于内容的图像检索中,纹理特征是一种重要而又难以描述的特征。为提高图像检索中纹理特征的提取效率,通过对Gabor滤波器滤波特点的研究,提出一种基于多尺度Gabor小波纹理的图像检索方法。设计了一组具有多种尺度和多个方向的滤波器组,选择并优化滤波器组的各参数,对图像进行滤波和特征提取。设计并实现了一个基于Gabor纹理...

Application of Multi-scale Gabor Wavelet Transform in Image Retrieval

Texture is a very important feature in content-based image retrieval,which is difficult to describe.To improve the efficiency of texture feature extraction in image retrieval,the structure of Gabor filter banks is studied,and an approach to texture images retrieval based on multi-scale Gabor wavelets transform is proposed.A group of Gabor filters with multi-scale and multiple directions is designed,and the parameters are optimized before image filtering and feature extraction.An image retrieval system based...
