This paper advances Jim Mutch' s proposed model,based on the multi- size and multi- orientation selecting trait of dual- tree complex wavelet translation.It improves the speed.And feature vector,that is size- invariant,rotating invariant and position invari- ant, can be obtained.Finally,support vector machine is used to classify.The result of the experiment on Caltech101 face images indi- cates that the proposed method has good classification performance.
