matlab人脸特征定位代码SpecDiff欺骗检测器 该存储库包含一个示例代码,该示例代码计算出我们的IJCB论文中提出的SpecDiff描述符,以执行面部表情攻击(欺骗)检测。 SpecDiff描述符利用面部图像的镜面反射和漫反射,无需大型训练数据库或高性能计算系统,即可进行快速,准确的欺骗检测。 *十月2020年更新:我们的论文获得了IJCB 2020 Google PC Chairs Choice最佳论文奖。 经过测试的计算环境 MATLAB R2017b 示例代码教程 运行主脚本“ SpecDiff_main.m”。 该脚本会加载一对示例照片(使用闪光灯和不使用闪光灯拍摄),以计算SpecDiff描述符。 带有径向基函数(RBF)内核的支持向量机(SVM)将描述符分为实时或欺骗两种类别之一。 分类分数的正值和负值分别表示实时分类和欺骗分类。 结果图 文件和目录 SpecDiff_main.m 主脚本将预处理应用于示例照片对,并将其分类为实时或欺骗类。 load_facial_images.m 加载一对面部照片,一张带有闪光灯,另一张不带有闪光灯。 预处理程序 应用本文中描述的
