摘要: 本文給出了一種新的圖象紋理分析法快速特征濾波法。在Ade特征濾波法基礎(chǔ)上,本文應(yīng)用實(shí)對(duì)稱矩陣特征值表示特征向量相對(duì)于該矩陣的分布性質(zhì),以及卷積結(jié)合律,最終導(dǎo)出了快速特征濾波器。使Ade的特征濾波法中的nn個(gè)濾波器在快速特征濾波法中變?yōu)橐粋€(gè)濾波器,從而增快了計(jì)算速度和減少了存貯空間。

Abstract: 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. -
