| 摘 要： | 结合小波系数统计特性的方法进行图像检索。由于小波系数提供了重要的方向信息,图像的小波系数的统计分布具有广义高斯分布特性。利用小波变换系数的统计特性,描述图像子带小波系数统计的特征矢量。结果表明,色度矩和小波系数统计特性相结合是一种有效的图像检索方法。

| Abstract: | Combined two techniques of chromaticity moments technique and statistical distribution of wavelet transformation coefficients for content-based image retrieval(CBIR).The wavelet coefficients provide important directional information,the statistics of image wavelet coefficients is generalized Gaussian distribution.This approach forms the feature vector of the image by taking advantage of the statistical distribution of wavelet transformation coefficients.Experimental result show that an efficient image retri... |
