一种新的基于Schur分解的Fisher鉴别分析方法

A New Method of Fisher Discriminant Analysis with Schur Decomposition

特征抽取是模式识别研究领域的一个热点。本文提出了一种新的基于Schur分解的Fisher鉴别分析的特征抽取方法。此方法引入了零空间的概念,指出了前人算法中的不足之处;给出了一个完整的基于Schur分解的Fisher鉴别分析方法。ORL人脸数据库上的实验表明了该方法的有效性。

Feature extraction is one of the hot topics in the field of pattern recognition. In this paper, we point out the weakness of the previous methods anda new method of Fisher discriminant analysis with Schur decomposition is proposed. Conception of null space is introduced in this paper. Experimental results on ORL face database indicate that the proposed method is valid.
