| Abstract: | A face recognition method based on 2D Principal Component Analysis（2DPCA） and compressive sensing is introduced in this paper.The 2DPCA is used to obtain the feature vectors and the compressive sensing is used to get the sparse representation of the test image given enough training images.The measure matrix is composed of the feature vectors of all training images and the feature vector of each test image is the observation value,then the encoding signal of the test image,which will be used for face recognition,can be obtained by using the L1 norm minimization.Experimental results indicate that the recognition rate based on 2DPCA and compressive sensing is higher than the recognition rate using other methods. |
