The feature ext ract ion is the most important and fundamental problem in image recognition. T he alg ebraic feature ex t ract ion is an ef fect ive metho d of the feature extr act ion. In this paper, a novel algebraic feature ex t ract ion method is presented. At first the eig en mat rix ( EM) o f the imag e is defined, then the EM is used for ex t ract ing the algebraic featur e. T his paper pro ved that this algebraic feature has some important pro pert ies o f algebr aic and g eomet ric inv ar iance. As an ex ample, this method is used for facial image recog nit ion. T he ex perimental result shows that this method is ef fectiv e.
