摘要
本文给出了一种新的图象纹理分析法——快速特征滤波法。在Ade特征滤波法基础上,本文应用实对称矩阵特征值表示特征向量相对于该矩阵的分布性质,以及卷积结合律,最终导出了快速特征滤波器。使Ade的特征滤波法中的n×n个滤波器在快速特征滤波法中变为一个滤波器,从而增快了计算速度和减少了存贮空间。
A new texture analysis method on image-fast eigenfiltering method is presented.Based on eigenfilters proposed by Ade, with which the eigenvalues of the real symmetric matrix represent distribution of the eigenvectors related to the matrix, and by using associative law of convolution, the fast eigenfilters are derived. In fast eigenfiltering method, n × n eigenfilters in Ade's filtering method merge into one filter, which can speed up the computation and reduces memory space.
