| 摘 要： | 以整数小波变换为基础,提出了一种综合颜色和空间特征的图像检索算法.该算法首先对图像做整数小波变换,提取其低频系数矩阵中环形区域的F-范数作为颜色特征;然后对低频分量分块并编码,利用马尔可夫链特性提取一步转移概率矩阵作为空间特征;再综合利用上述两个特征计算图像间的相似度,并进行彩色图像检索.通过对不同类型图像的检索对比实验结果表明,这种图像检索方法是行之有效的.

| Abstract: | According to the integer wavelet transform, a new method of content-based image retrieval is presented, which integrates color and spatial features. Firstly, the circular region F-norms in low frequency band of integer wavelet transform are extracted as color feature. Secondly, low frequency band of integer wavelet transform is segmented into blocks and encoded, the transition probability matrix utilizing characteristic of Markov chain is as spatial information. Finally, the similarities between color image... |
