Abstract:

In order to reduce the effect of illumination changes on face recognition accuracy, we propose a face recognition method combining homomorphic filters with Radon transform. Firstly, we filter face images by homomorphic filters, then Radon transform is implemented and the feature dimension is reduced with 2DPCA/2DLDA.Experiment results on Yale and PIE face databases show that the recognition accuracy of the proposed method is better than the 2DPCA and 2DLDA methods under large illumination changes.Key words:
