一种基于二代Curvelet和2D Log-Gabor滤波器的多模特征层融合识别方法

An Algorithm for Multimodal Biometrics Feature Level Fusion Recognition Based on the Second-Generation Curvelet and 2D Log-Gabor Filter

  • 摘要: 针对单模生物特征识别在实际应用中易受干扰、识别率低且无法达到零错误识别的问题,提出一种基于二代Curvelet和2DLog-Gabor滤波器的人脸与虹膜特征层融合识别算法.该方法利用二代曲波变换提取人脸特征,用2DLog-Gabor幅值法提取虹膜特征,通过PCA降维单模特征向量,在特征层进行融合,通过SVM分类识别融合特征向量.在ORL人脸库和CISIA虹膜库构成的多模生物特征库上进行测试.实验结果表明:该算法正确识别率能达到100%,较单模人脸、单模虹膜识别方法的识别率均提高3.33%,为多模生物特征识别提供了一种有效模型.

     

    Abstract: For single-modal biometric system is susceptible to interference in appliacation, with low recognition rate, and not able to achieve zero error identification, a new fusion recognition approach in feature level of face and iris is proposed, based on the second-generation Curvelet and 2D Log-Gabor filtering.In the proposed approach, the second generation Curvelet is employed to extract face information, and amplitudes of 2D Log-Gabor are used to extract iris information.Then we use PCA to reduce the dimention of single-modal feature vectors, combine them in feature level, and distinguish fusion feature vectors by SVM.Experimental results on ORL face database and CASIA iris database show that: the correct fusion recognition rate can reach 100%, improved both 3.33% compared with single face feature and single iris feature, and the proposed algorithm is an effective model for multimodal biometric recognition.
