mmod_human_face_detector.dat是训练好的模型,可以从这里下载:

http://dlib.net/files/mmod_human_face_detector.dat.bz2

输入参数:

1. 模型dat文件

2.要检测的人脸图片

import dlib

    This detector returns a mmod_rectangles object. This object contains a list of mmod_rectangle objects.
    These objects can be accessed by simply iterating over the mmod_rectangles object
    The mmod_rectangle object has two member variables, a dlib.rectangle object, and a confidence score.

    It is also possible to pass a list of images to the detector.
        - like this: dets = cnn_face_detector([image list], upsample_num, batch_size = 128)
    In this case it will return a mmod_rectangless object.
    This object behaves just like a list of lists and can be iterated over.
