Abstract

Glasses as the most common occluding object in facial images have a greatly influence on face recognition performance.In order to improve the recognition rate with glasses,the glasses need to be removed from frontal facial image.An algorithm based on principle component analysis and independent component analysis is proposed to extract the second order statistics feature and higher-order information,which depicting well the detailed features of a face.Gray compensating algorithm is adopted in order to remedy distortion,for which the image that wear glasses do not participate in the training of the feature space.Iterative compensation algorithm is used for face reconstruction.The simulation experimental results show that through the Yale face database,the synthesize images using the proposed method have not the signs of glasses,looks more natural,improve effectively the characteristics of face images with glasses and face recognition rate.

基于PCA/ICA和误差补偿的眼镜去除研究

眼镜作为人脸图像中最常见的遮挡物，对人脸识别性能影响很大。为了提高戴眼镜的识别率，需要将眼镜从正面人脸图像中去除。提出了一种基于主成分分析和独立成分分析的人脸二阶统计特征和高阶信息提取算法，较好地刻画了人脸的细节特征。为了消除畸变，采用了灰度补偿算法，戴眼镜后的图像不参与特征空间的训练。人脸重建采用迭代补偿算法。仿真实验结果表明，通过耶鲁人脸数据库，采用本文方法合成的图像没有了戴眼镜的痕迹，看起来更加自然，有效地提高了戴眼镜人脸图像的特征和人脸识别率。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
