- Abstract:
-
The accuracy of face recognition is low under unconstrained conditions. To solve this problem, we propose a new method based on deep learning and the weighted fusion of facial features. First, we divide facial feature points into five regions using an active shape model and then sample different facial components corresponding to those facial feature points. A corresponding deep belief network(DBN) was then trained based on these regional samples to obtain optimal network parameters. The five regional sampling regions and entire facial image obtained were then inputted into a corresponding neural network to adjust the network weight and complete the construction of sub-networks. Finally, using softmax regression, we obtained six similarity vectors of different components. These six similarity vectors comprise a similarity matrix, which is then multiplied by the weight vector to derive the final recognition result. Recognition accuracy was 97% and 91.63% on the ORL and WFL face databases, respectively. Compared with traditional recognition algorithms such as SVM, DBN, PCA, and FIP+LDA, recognition rates for both databases were improved in both constrained and unconstrained conditions. On the basis of these experimental results, we conclude that the proposed algorithm demonstrates high efficiency in face recognition.
