基于间隔Fisher分析的几种改进算法

摘要

在间隔Fisher分析（MFA）的基础上，提出了三种改进算法：正则化MFA，目标函数为减式的MFA和基于零空间的MFA．为了检验算法的有效性和先进性，针对AVIRIS遥感图像进行了实验．实验结果表明，所提算法均优于MFA．%Three kind of improved algorithms, based on marginal Fisher analysis (MFA), are proposed in this paper, which are regularized marginal Fisher analysis, marginal Fisher analysis with subtractive objective function and marginal Fisher analysis based on the null space. Experiments on AVIRIS remote sensing image are made in order to test the validity and advantage of the methods presented in this paper. The experimental results demonstrate that our proposed algorithms are better than MFA.
