人脸识别所用的模型
推荐使用(推荐优先级同顺序)：GhostFaceNet, ArcFace
Deepface is a hybrid face recognition package. It currently wraps many state-of-the-art face recognition models: 
model_name	Declared LFW Score  是否可用     备注
VGG-Face        98.9%             可用
Facenet         99.2%             可用 
Facenet512      99.6%             可用     效果似乎不好
OpenFace        92.9%             可用
DeepID          97.4%             可用
Dlib            99.3%            不可用 
SFace           99.5%             可用
ArcFace         99.5%             可用       重点测试**（阈值应该可以设置小一点）   
GhostFaceNet    99.7%             可用       重点测试**  
Human-beings    97.5%            不可用

The default configuration uses GhostFaceNet model.

推荐(优先级同顺序)：retinaface, mtcnn, opencv, ssd
backends = {
    "opencv": OpenCv.OpenCvClient,  可用，效果一般，容易找不到人脸
    "mtcnn": MtCnn.MtCnnClient,   可用，效果挺好
    "ssd": Ssd.SsdClient,   可用，容易找到太多人脸
    "dlib": Dlib.DlibClient,  不可用，Dlib is an optional detector, ensure the library is installed.Please install using 'pip install dlib'
    "retinaface": RetinaFace.RetinaFaceClient,  可用，效果挺好
    "mediapipe": MediaPipe.MediaPipeClient,  未知，MediaPipe is an optional detector, ensure the library is installed.Please install using 'pip install mediapipe'
    "yolov8": Yolo.YoloClient,    不可用，Yolo is an optional detector, ensure the library is installed.                 Please install using 'pip install ultralytics'
    "yunet": YuNet.YuNetClient,  未知，没下载model ck
    "fastmtcnn": FastMtCnn.FastMtCnnClient,  不可用，FastMtcnn is an optional detector, ensure the library is installed.Please install using 'pip install facenet-pytorch'
}

这是计算不同人脸相似度时使用的函数，直接使用代码中默认的既可，无需更改
distance_metric = ['euclidean_l2','cosine','euclidean']
author: Euclidean L2 form seems to be more stable than cosine and regular Euclidean distance based on experiments.
