摘要:

为了减轻光照变化对人脸识别精度的影响,提出了一种结合同态滤波器与Radon变换的人脸识别方法。首先用高斯同态滤波器对人脸图像进行处理,然后进行Radon变换,将变换得到的Radon特征用2DPCA/2DLDA进行降维。在Yale和PIE人脸数据库上的实验结果表明,提出的方法在光照变化较大时,其识别精度远高于2DPCA和2DLDA,是一种高精度的人脸识别算法。

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:
