摘要
提出了一种用整数小波系数检索纹理图像的方法.纹理图像的主要特征表现在细节部分,而高频部分的小波系数体现了图像的细节,所以从这些小波系数中提取的特征,能够表征纹理图像的主要特性;实验结果表明,用该方法检索纹理图像,能够达到较好的检索效果,并且对亮度不敏感,这一特点是传统的纹理分析方法难以达到的.
A texture image retrieval method using the integertointeger wavelet coefficient is proposed. As the main features of the texture image are present in the details and the high pass of the WT coefficients denotes the details of the image, the features deduced from WT Coefficients can be used to retrieve the texture image. Better indexing results can be obtained based on this method, which are not sensitive to luminance. These virtues cannot be found in the traditional literature.
