    • A face recognition that is robust to external illumination variations is provided. The face recognition apparatus includes a face localizer extracting a predetermined number of feature points from a facial region extracted from an input image, a Gabor filter unit applying a set of Gabor filters with a plurality of orientations and frequencies to each of the facial feature points in order to obtain filter responses and generates a one-dimensional (1-D) vector consisting of the filter responses, a training data set storage storing the 1-D vector when the gaber-filtered 1-D vector is obtained from a training image, and a binary classifier generating a binary determination criterion using the stored 1-D vector, applying the binary determination criterion to the 1-D vector when the gaber-filtered 1-D vector is obtained from an image to be recognized and determining the identity of the image to be recognized.
    • 提供了对外部照明变化稳健的人脸识别。 面部识别装置包括面部定位器,从输入图像提取的面部区域提取预定数量的特征点; Gabor滤波器单元,将具有多个取向和频率的Gabor滤波器组应用于每个面部特征点, 为了获得滤波器响应并产生由滤波器响应组成的一维(1-D)矢量,当从训练图像获得加速器滤波的1-D矢量时存储存储1-D矢量的训练数据集存储器, 以及二进制分类器,其使用所存储的1-D矢量生成二进制确定标准,当从要识别的图像获得加载器滤波的1-D矢量时,将二进制确定标准应用于1-D矢量,并且确定 要识别的图像。
