基于颜色和纹理特征的图像检索技术研究

为改善单一特征图像检索方法的局限性和传统综合特征检索方法计算复杂度高的问题,提出一种综合特征的图像检索新方法:将Tamura纹理特征与抗几何形变的小波变换纹理分析方法相结合提取出13个纹理特征分量,在小波分解得到的低频区域中进行颜色直方图的提取,从而实现了颜色和纹理特征相结合的图像检索系统.实验表明,该方法在不明显增大计算量的情况下比单一特征的图像检索具有更好的检索效果.

Research of Image Retrieval Based on Color and Texture Feature

In order to improve the limitations of a single feature image retrieval method and the problem of traditional method which integrated features image retrieval has high complexity,it brought up a new retrieval method of combined features:use Tamura texture feature combined with a method of wavelet transform analysis of anti-geometric distortions to extracted 13-componet texture features,after the Daubechies3 wavelet factorize,extract color histogram from the low-frequency region to achieve color and texture ...
