New face recognition method based on improved modular PCA
2011
An improved modular PCA(Principal Component Analysis) method,that is modular PCA method based on independence of feature extraction,is proposed.The original images are divided into sub-images in proposed approach.Then each kind of sub-images at the same position have been disposed by PCA independently,the distance between the corresponding sub-images of the test sample and the train sample can be given.Finally,the distance between the test sample and the train sample can be caculated by adding all these distances between the sub-images together,the nearest distance classification is used to distinguish each face.Experimental results on ORL face database and Yale face database indicate that the improved modular PCA is obviously superior to that of general modular PCA.
