In this paper we present a unified system for face verification (is this the same person), recognition (who is this person) and clustering (find common people among these faces). Our method is based on learning a Euclidean embedding per image using a deep convolutional network. The network i...
2020-03-ICML Leveraging Frequency Analysis for Deep Fake Image Recognition 论文统计了数据集的DCT频谱图,如下图所示,发现真实图像和伪造图像存在明显差异,一是伪造图像会展现更多的高频信息,二是伪造图像会出现网格状条纹。 同样,论文进一步分析了这种差异是由于上采样操作造成的,并实验了不同的上采样操作的效果,如...
02 研究历程 60 年代末,Chan 等人[1]发表了自动人脸识别(Automated Face Recognition,AFR)研究技术报告,以人脸特征点的间距、比率等作为特征,建成了一个人脸识别系统。以此为时间点,越来越多的学者致力于人脸识别的研究。 第一个阶段,是上世纪 60 年代到 90 年代。这一阶段的人脸识别研究主要是集中于人工设计的特...
In this work, deep CNN based model have been suggested for face recognition. CNN is employed to extract unique facial features and softmax classifier is applied to classify facial images in a fully connected layer of CNN. The experiments conducted in Extended YALE B and FERET databases for ...

nativeInit() 就是创建一个 Native 的 FaceTracker 对象,然后将该对象的地址返回给上层: extern "C" JNIEXPORT jlong JNICALL Java_com_face_recognition_FaceTracker_nativeInit(JNIEnv *env, jobject thiz, jstring model_path) { const char *path = env->GetStringUTFChars(model_path, 0); // 初始化Fac...

【Face recognition】人脸识别实战 实验结果 图片发自简书App 深度神经网络一般使用CNN,而CNN的改进又有Resnet残差网络,引入shortcut connection,以避免梯度弥散和爆炸,当前层让前面好多层的特征也可以随着前一层一起输入到当前层网络中去。 比较成熟的网络现在有VGG-16等。 训练过程有一个叫Triplet loss的损失函数,用...
面部关键点也称为面部地标,通常指定面部的鼻子,眼睛,嘴巴等区域,该面部按68个关键点分类,并带有该坐标的坐标(x,y)。使用面部关键点,可以实现面部识别,情绪识别等。 点代表关键点 选择数据集: 由于Udacity已经提供了YouTube Faces数据集,因此将使用它。它是一个数据集,包含3,425个面部视频,旨在研究视频中无约束的...
