注意事项

该库中包含了两个网络,分别是retinaface和facenet。二者使用不同的权值。 在使用网络时一定要注意权值的选择,以及主干与权值的匹配。

所需环境

tensorflow-gpu==1.13.1
keras==2.1.5

文件下载

预测所需的权值文件可以在百度云下载。

预测步骤

  1. 本项目自带主干为mobilenet的retinaface模型与facenet模型。可以直接运行,如果想要使用主干为resnet50的retinafa和主干为inception_resnetv1的facenet模型需要。
  2. 在retinaface.py文件里面,在如下部分修改model_path和backbone使其对应训练好的文件。
_defaults = {
    "retinaface_model_path" : 'model_data/retinaface_mobilenet025.h5',
    #-----------------------------------#
    #   可选retinaface_backbone有
    #   mobilenet和resnet50
    #-----------------------------------#
    "retinaface_backbone"   : "mobilenet",
    "confidence"            : 0.5,
    "iou"                   : 0.3,
    #----------------------------------------------------------------------#
    #   是否需要进行图像大小限制。
    #   输入图像大小会大幅度地影响FPS,想加快检测速度可以减少input_shape。
    #   开启后,会将输入图像的大小限制为input_shape。否则使用原图进行预测。
    #   keras代码中主干为mobilenet时存在小bug,当输入图像的宽高不为32的倍数
    #   会导致检测结果偏差,主干为resnet50不存在此问题。
    #   可根据输入图像的大小自行调整input_shape,注意为32的倍数,如[640, 640, 3]
    #----------------------------------------------------------------------#
    "retinaface_input_shape": [640, 640, 3],
    "letterbox_image"       : True,

    "facenet_model_path"    : 'model_data/facenet_mobilenet.h5',
    #-----------------------------------#
    #   可选facenet_backbone有
    #   mobilenet和inception_resnetv1
    #-----------------------------------#
    "facenet_backbone"      : "inception_resnetv1",
    "facenet_input_shape"   : [160,160,3],
    "facenet_threhold"      : 0.9,
}
  1. 运行encoding.py,对face_dataset里面的图片进行编码,face_dataset的命名规则为XXX_1.jpg、XXX_2.jpg。最终在model_data文件夹下生成对应的数据库人脸编码数据文件。
  2. 运行predict.py,输入下述文字,可直接预测。

  1. 利用video.py可进行摄像头检测。
